The dinosaur of the day: Agathaumas
- Ceratopsid that lived within the Late Cretaceous in what’s now Wyoming, U.S.
- Doubtful genus (nomen dubium) as a result of not many fossils discovered, and of these discovered, nothing diagnostic
- Not a lot discovered, solely hip bones, hip vertebrae, and ribs
- Bones are a part of the AMNH collections
- Estimated to be about 30 ft (9 m) lengthy, and weigh 6 tonnes
- Present in 1872, by Fielding Bradford Meek and Henry Martyn Bannister, who had been on the lookout for fossil shells (labored for Ferdinand Vandeveer Hayden’s Geological Survey of the Territories)
- They let Edward Cope know, and Cope printed a reputation and outline later that 12 months, 1872
- First named ceratopsian
- When it was found, it was the most important identified land animal
- Identify means “nice marvel”
- Cope named it Agathaumas sylvestris (“marvelous fossil dweller”) as a result of it was so massive, and since the fossils had been present in rock that indicated a forest habitat (leaf fossils)
- In 1873 Cope stated it was “the wreck of one of many princes amongst giants”
- As a result of Agathaumas was the primary named ceratopsian (earlier than ceratopsians had been a factor), Cope didn’t know how you can classify it, and regarded it to be a hadrosaur till Marsh described Triceratops in 1889
- Different species had been thought-about to be Agathaumas (flabellatus, milo, monoclonius, mortuarius, prorsus, sphenocerus) however had been later discovered to be both nomen dubium or included with different genera (three of them grew to become Triceratops)
- Probably a synonym of Triceratops, however laborious to inform as a result of not sufficient fossils
- No cranium materials discovered for Agathaumas (would assist to find out if it’s a separate genus)
- Charles Knight illustrated Agathaumas in 1897, based mostly on the partial cranium of Agathaumas sphenocerus (later generally known as Monoclonius sphenocerus after which probably Styracosaurus), and gave it a big nasal horn and small horns over the eyes
- Knight’s portray was used as a mannequin for Agathaumas within the 1925 silent movie, The Misplaced World
- Portray was of Agathaumas sphenocerus, not the sort species Agathaumas sylvestris
Enjoyable Truth:
Birds have very totally different leg proportions from the extinct theropod dinosaurs we all know and love, so even flightless birds will not be an awesome mannequin for theropod motion.
