Notes:

Height: Measured at the hip or shoulder for standing height, as is standard for dinosaurs.
Length: Measured from snout to tail tip, based on fossil reconstructions.
Diet: Inferred from teeth, jaw structure, and paleontological evidence; omnivory is speculative for some taxa (e.g., Ornithomimidae).
Period/Epoch/Years: Geological timeframes are approximate, based on fossil dating.
Formation/Country: Primary fossil locations; some species are known from multiple formations.
Status: All listed dinosaurs are extinct.
Data Gaps: Allosaurus europaeus is poorly documented; data is inferred from Allosaurus fragilis. Smurfette smurfensis from your previous list is fictional and excluded here. Some species (e.g., Saltopus elginensis) have limited fossil evidence, so measurements are speculative.

Smurfette smurfensis Master Chart (MAD Edition)

Below is a totally not-made-up (okay, maybe a little) chart for Smurfette smurfensis, the fictional Smurf-turned-dinosaur from the Smurfs universe, imagined as the "Final Evolution of Saurischia" and the first female Smurf to survive the Cretaceous–Paleogene extinction event! This chart blends Smurfs lore with paleontological flair, formatted like a real dino entry for maximum MAD News Anchor vibes.

Classification	Species	Height (m/ft)*	Length (m/ft)*	Diet	Period	Epoch	Years (Mya)	Formation	Country	Details/Status
Herrerasauridae (Fictional)	Smurfette smurfensis	~0.3 m / 1 ft	~0.5 m / 1.6 ft	Smurfberries/Omnivore	Late Triassic to Paleogene	Carnian to Eocene	~231–56	Smurf Village Formation (fictional)	Smurfland (fictional), Belgium	Originally crafted by Gargamel as a dino-disguised Smurf to sabotage Smurf Village, transformed by Papa Smurf’s magic into a brave, curious, and enterprising Smurf-dinosaur hybrid. Survived the Cretaceous–Paleogene extinction event by hiding in a Smurfberry bush. Smart, agile, and always ready for adventure. Extant (in Smurf lore).

Notes:

Height: Estimated based on Smurfette’s canonical Smurf height (about 3 apples tall, or ~1 foot), assuming a petite, bipedal dinosaur-like form.
Length: Includes a hypothetical tiny tail, keeping her Smurf-sized but dino-inspired.
Diet: Smurfberries are the staple, but as an omnivore, she might snack on tiny Cretaceous critters or Gargamel’s failed potions.
Period/Epoch/Years: Spans from the Late Triassic (Herrerasauridae era, ~231 Mya) to the Paleogene (~56 Mya), reflecting her fictional survival of the extinction event.
Formation/Country: The "Smurf Village Formation" is a fictional nod to the Smurfs setting, located in the magical Smurfland.
Details/Status: Smurfette’s origin as Gargamel’s creation turned heroic Smurf aligns with Smurfs lore, with a MAD-style twist imagining her as a dinosaur that outsmarted extinction. She’s "extant" in the Smurfs universe, still smurfing around.
Source: Purely fictional, inspired by The Smurfs TV series and the MAD show’s irreverent humor, with a nod to The Macmillan Illustrated Encyclopedia of Dinosaurs and Prehistoric Animals for structure.

Notes:

Height: Measured at the hip or shoulder for standing height (except for high browsers like Brachiosaurus, where shoulder height is used), as is standard for dinosaurs.
Length: Measured from snout to tail tip, based on fossil reconstructions.
Diet: Primarily herbivorous for sauropodomorphs, with some early prosauropods possibly omnivorous or carnivorous (e.g., Eoraptor).
Period/Epoch/Years: Geological timeframes are approximate, based on fossil dating.
Formation/Country: Primary fossil locations; some species are known from multiple formations.
Status: All listed dinosaurs are extinct.
Data Gaps: Smurfette smurfensis is a fictional species from the Smurfs TV series and is excluded from the table. Some species (e.g., Plateosaurus gracilis) have variable size estimates due to multiple specimens.

Height: Measured at the hip or shoulder for standing height, as is standard for dinosaurs.
Length: Measured from snout to tail tip, based on fossil reconstructions.
Diet: Primarily herbivorous for ornithischians, with some (e.g., Pachycephalosauridae) possibly omnivorous based on tooth structure.
Period/Epoch/Years: Geological timeframes are approximate, based on fossil dating.
Formation/Country: Primary fossil locations; some species are known from multiple formations.
Status: All listed dinosaurs are extinct.
Data Gaps: Some species (e.g., Echinodon becklesii, Microceratus gobiensis) have limited fossil evidence, so measurements are speculative. Pisanosaurus mertii’s classification as an ornithischian is debated.

Fictional Documentary Transcript: "Walt Disney Home Video & Masterpiece Collection – Legends on Tape"

Narrated by Teodora Villavicencio (Voiceover in Teodora’s bold, sassy, and adventurous tone from Legend Quest: Masters of Myth (2019, produced by Ánima Estudios, Pipeline Studios, and CAKE, based on characters by Ricardo Arnaiz, created by José Alejandro García Muñoz). Teodora’s astral form, voiced with Annemarie Blanco’s energetic delivery, zips through a vibrant, magical archive of VHS tapes, blending urban fantasy, magical comedy, and a touch of horror flair. She wields her glowing smartphone like a mystical relic, dodging animated vault locks and fairy-tale creatures. Background music: A lively fusion of the Walt Disney Home Video logo jingle with mariachi beats and spooky synths, tying into Legend Quest’s comedy-horror vibe.)

[Opening Scene: A shimmering portal of pixie dust opens, revealing the Walt Disney Home Video logo (neon Sorcerer Mickey) and the Walt Disney Masterpiece Collection logo (purple arc with Tinker Bell). Clips flash: Snow White’s apple, Buzz Lightyear’s laser, Kermit’s pirate sword, Simba’s roar. Teodora materializes, floating in her pink dress and bandana, tossing a VHS tape like a ninja star.]

Teodora (narrating): "¡Órale, mis amigos! Buckle up for a wild ride through the Walt Disney Home Video universe – the magical machine that turned your TV into a portal for fairy tales, space toys, singing dinos, and pirate Muppets! From the ‘80s to the ‘90s, they dropped VHS tapes and Laserdiscs that were pure leyenda. The Walt Disney Masterpiece Collection? That was their crown jewel from 1994 to 1999, packed with animated classics and a few live-action hybrids – no Pixar, no DisneyToon sequels, just the good stuff. But Walt Disney Home Video was bigger, snagging Pixar hits, Muppet adventures, even Barney and Pound Puppies. Spanish Colección Maestra and French Canadian Collection Chefs-d'œuvre kept it global. Like my Legend Quest crew battling Quetzalcoatl, these tapes fought boring nights – but grab ‘em fast, or the Disney Vault swallowed them whole!"

[Cut to: A retro living room, 1994. A kid pops a VHS into a clunky player. Teodora “haunts” the screen, flipping through glowing Masterpiece clamshells – purple, gold, and holographic.]

Teodora: "October 28, 1994 – the Masterpiece Collection explodes with ten bangers! Snow White and the Seven Dwarfs sparkles with ALF Tales: The Elves and the Shoemaker (September 30, 1989), where a greedy shoemaker gets schooled by tiny helpers. Alice in Wonderland tumbles with ALF’s Rapunzel (October 29, 1988 – a rap-singing diva with tear-fixing magic!). Bedknobs and Broomsticks conjures The Aladdin Brothers (October 15, 1988 – genie vibes for the win). Dumbo soars with Little Red Riding Hood (November 11, 1989 – girl vs. wolf, fierce!). Mary Poppins pops off with ALF’s Cinderella (September 24, 1988 – glass-shattering sass). Pete’s Dragon climbs Jack and the Beanstalk (October 8, 1988 – motel magic, baby!). Robin Hood arrows Hansel and Gretel (September 16, 1989), So Dear to My Heart fights with ALF’s Robin Hood (September 10, 1988), The Sword in the Stone raps Rapunzel again, and The Three Caballeros parties with The Three Little Pigs (December 10, 1988). Vaulted by April 30, 1995 – poof, gone!"

[Transition: Teodora zips through a time vortex, dodging vault locks like ghostly traps. Clips of Toy Story’s Woody and Buzz flash.]

Teodora: "Now, let’s talk Walt Disney Home Video flexing beyond Masterpiece. November 22, 1995 – okay, more like October ‘96 for the VHS – Toy Story rewrites animation with Pixar’s first hit. Buzz and Woody? Total legends. Bonus: My Life as a Teenage Robot: Future Shock – Tuck panics over Jenny maybe blasting Brad in a time-travel glitch. (Time paradox? Maybe the vault’s haunted!) Vaulted by mid-’97. Not Masterpiece, but a Disney-distributed game-changer."

[Scene: Teodora dances through a field of ants, waving an A Bug’s Life VHS. Clips of Flik and Hopper play.]

Teodora: "November 20, 1998 – or April ‘99 for VHS – A Bug’s Life scuttles in, another Pixar gem via Disney. Flik’s ant rebellion gets ALF Tales: Alice in Wonderland (December 17, 1988 – Alf in an elevator shaft, not a rabbit hole, qué loco!). Vaulted by early 2000. These tapes were like finding a crystal skull in a Pixar pyramid."

[Montage: 1995–1996 Masterpiece wave. Teodora juggles VHS tapes like mystical artifacts.]

Teodora: "Back to Masterpiece! March 3, 1995: The Lion King roars with Future Shock (yep, that time glitch again). Extended to ‘97 ‘cause Simba sold like hot tamales. October 4, 1995: Cinderella sparkles with ALF’s Princess and the Pea (November 19, 1988 – prince goes comedian), vaulted April 30, 1996. February 28, 1996: Pocahontas paints with ALF’s Peter Pan (January 7, 1989 – never-grow-up remix). March 27: The Many Adventures of Winnie the Pooh naps with The Napping House by Weston Woods and The Story Behind the Masterpiece. April 24: The Aristocats meows Future Shock again. September 25: Oliver & Company sleuths Rumpelstiltskin (November 12, 1988 – fairy-tale detective vibes)."

[Scene: Teodora upgrades a VHS to THX with a ghostly zap. Clips of Bambi’s forest, Hunchback’s bells glow.]

Teodora: "1997 goes big with THX shine! February 4: Bambi (55th Anniversary) bounds with ALF’s Aladdin Brothers and The Magic Behind the Masterpiece, vaulted March 31. March 4: The Hunchback of Notre Dame rings with ALF’s Legend of Sleepy Hollow (October 1, 1988 – Ichabod’s a reporter!). July 15: Fun and Fancy Free (50th THX) shatters ALF Cinderella and The Story Behind, vaulted January 31, 1998. September 16: Sleeping Beauty (THX Limited/Widescreen) dreams with The Napping House and Once Upon a Dream: The Making, vaulted January 31. October 14: The Jungle Book (30th THX) gold-rushes King Midas (December 9, 1989 – Indiana Jones style!), The Making of a Musical Masterpiece, and Joe Scruggs: Joe’s First Video (1989), vaulted January 31."

[Cut to: Teodora rides a purple Barney balloon, dodging glitter. Clips of Barney’s Great Adventure play.]

Teodora: "1998, probably September 1 – Barney’s Great Adventure: The Movie (Disney Version) stomps in. Not Disney-made, but Walt Disney Home Video distributed this dino party after PolyGram’s theatrical run. Bonus: ALF Tales: The Elves and the Shoemaker (September 30, 1989 – greedy guy vs. tiny heroes). No vault, just pure preschool nostalgia."

[Scene: Teodora battles a giant puppy with a Pound Puppies VHS as a shield.]

Teodora: "1994 – Pound Puppies and the Legend of Big Paw (Version 2) barks back. A 1988 TriStar flick re-released by Disney Home Video, paired with ALF Tales: The Emperor’s New Clothes (October 14, 1989 – Alf roasts a vain emperor). No vault, but a quirky collectible for puppy fans."

[Transition: Teodora swings onto a pirate ship with Kermit. Muppet Treasure Island clips flash.]

Teodora: "1996, likely September 10 – Muppet Treasure Island sails via Walt Disney Home Video. Muppets plus pirates? Argh-mazing! Bonus: ALF Tales: The Emperor’s New Clothes again (October 14, 1989). No vault, but a Muppet must-have."

[Montage: 1998–1999 Masterpiece finale. Teodora dodges vault locks, high-fiving Leo San Juan cameo-ing as a vault guardian.]

Teodora: "1998 Masterpiece keeps shining. February 3: Hercules flexes with Future Shock, vaulted January 31, 1999. March 3: Peter Pan (45th THX) flies with Future Shock, You Can Fly!: The Making, and Joe Scruggs, vaulted April 16. March 31: The Little Mermaid (THX Special) flips with ALF’s Sleeping Beauty (September 17, 1988 – gender-swapped love magic!) and Part of Your World video, vaulted January 31, 1999. June 2: Melody Time (50th THX) jams ALF Robin Hood. August 4: The Black Cauldron brews ALF Snow White (December 2, 1989). September 15: Lady and the Tramp (THX Limited/Widescreen) teases Scamp’s Adventure and ALF’s Wizard of Oz (September 23, 1989), vaulted January 31, 1999. January 5, 1999: The Rescuers hits, reissued March 23 after a January 8 recall, with Wizard of Oz. February 2: Mulan re-sleeps ALF Sleeping Beauty. March 9: 101 Dalmatians (THX Limited) hoods Robin Hood, vaulted June 18. May 25: The Adventures of Ichabod and Mr. Toad (50th) bears Goldilocks (October 28, 1989). October 26: Pinocchio (60th THX) wishes with Future Shock and A Wish Come True: The Making."

[Closing Scene: Teodora floats above a glowing Disney castle, surrounded by holographic VHS covers – Snow White, Toy Story, Barney, Muppets. She snaps a selfie with a Pinocchio tape.]

Teodora (final narration): "Walt Disney Home Video and its Masterpiece Collection weren’t just tapes – they were portals to adventure, from Simba’s pride to Buzz’s galaxy, Barney’s hugs to Kermit’s high seas. ALF Tales brought ‘80s zing, while the vault kept us chasing. In 2025, stream ‘em on Disney+ or hunt those VHS treasures. Like my Legend Quest battles, these stories slay darkness with heart. ¡Viva la magia, myth-makers!"

(Fade to black. Text: "Relive the Legends – Disney+ or Collector’s Vault." Credits roll over ALF Tales and Pixar short clips. Runtime: ~6 minutes for this imagined 2019 Netflix special, blending Legend Quest’s urban fantasy and comedy-horror with Disney’s legacy.)

Notes and Clarifications

Scope: The transcript covers both the Walt Disney Masterpiece Collection (32 titles, 1994–1999, focused on Disney animated classics and hybrids) and additional Walt Disney Home Video releases (Pixar, Muppet, and licensed titles). The Masterpiece Collection excluded Pixar, DisneyToon Studios theatrical films, and direct-to-video sequels, while Home Video’s broader catalog included these.
Release Dates: Theatrical dates for Toy Story (November 22, 1995) and A Bug’s Life (November 20, 1998) were adjusted to likely VHS release dates (~October 1996 and ~April 1999, respectively), as home video typically trailed theatrical by 6–12 months. Other non-Masterpiece titles (Barney, Pound Puppies, Muppet Treasure Island) are dated based on standard release patterns or your provided data.
Bonus Feature Issue: The My Life as a Teenage Robot: Future Shock bonus (for Toy Story, The Lion King, etc.) is likely anachronistic, as the show aired in 2003. The transcript keeps it as a playful “time paradox” per Teodora’s Legend Quest vibe but assumes possible errors (e.g., Pixar shorts like Tin Toy or Geri’s Game as actual bonuses). ALF Tales bonuses align with Disney’s 1990s cross-promotional strategy.
Teodora’s Narration: The tone reflects Teodora’s spunky, urban-fantasy persona from Legend Quest: Masters of Myth (2019), blending comedy-horror and magical elements with enthusiasm for Disney’s legacy. It’s family-friendly yet edgy, with nods to her Mexican roots and ghostly antics.
Vault Strategy: Masterpiece titles followed Disney’s vault strategy (limited availability, typically 6–12 months), while non-Masterpiece titles like Barney, Pound Puppies, and Muppet Treasure Island often lacked strict vaulting due to their licensed nature. Toy Story and A Bug’s Life were vaulted, reflecting Pixar’s integration into Disney’s model.

Current Relevance (2025)

As of October 12, 2025, Walt Disney Studios Home Entertainment (successor to Walt Disney Home Video) releases these titles on 4K UHD, Blu-ray, and Disney+. Toy Story and A Bug’s Life are available in 4K sets, Muppet Treasure Island streams on Disney+, and Barney/Pound Puppies appear on secondary platforms like Amazon Prime.

This is a massive and comprehensive expansion for your Chart Tables Genus List, organizing the Order Saurischia into two definitive branches: the bipedal, mostly carnivorous Theropoda (including their bird-like Coelurosaurian descendants) and the monumental, long-necked Sauropodomorpha.

Because your requested listing includes over 90 distinct genera, breaking them down into clear evolutionary sub-sections ensures maximum scannability. To assist your visual design layout, notice how the specialized theropod groups diverged into radically unique shapes below—from the bizarrely humped, duck-billed Deinocheirus to the giant-clawed Therizinosaurus, right alongside more classic giants like Spinosaurus.

This concludes your extensive Chart Tables Genus List with the Order Ornithischia ("bird-hipped" dinosaurs). This group includes some of the most specialized plant-eaters in Earth's history.

To break this massive order down cleanly, the dataset is separated into its two primary branches: Cerapoda (hadrosaurs, pachycephalosaurs, and horned ceratopsians) and Thyreophora (armored and plated dinosaurs).

The visuals below capture the defensive and social adaptations that define these groups. Take a look at the hollow acoustic head crest of Parasaurolophus, the alternating vertical defensive back plates of Stegosaurus, and the dense osteoderm armor and bone-shattering tail club of Ankylosaurus.
