I just found out that Land Before TIme XIII decided to add Therizinosaurs into the story
Which is interested, because they are a "Plant Eater" but are related to T-Rex and Raptors
...
There only problem? Compare these 2 images
They are kind of missing one of the most prominent
points of the Therizinosaur. It's giant claws. That is THE thing the Therizinosaur is known for. It had unusually massive claws on it's hands.
Not to mention, although the picture doesn't show it well, Therizinosaurs DID have sharp teeth. They just used them for eating plants rather than meat. Probably didn't grind them in their mounths.
Edit: Also, Therizinosaurs were a size comparable to a T-Rex, their forelimbs alone being 8 feet long. The whole animal was around 33 feet tall
Edit 2: Although, apparently they used a smaller species, the "
Beipiaosaurus" which was considerably smaller. LOL, oops.
But it still didn't look friendly
Edit 3: The land before time wiki uses the same picture of Therizinosaur I used above and describes Therizinosaur.
