Fossil Fact #6!!!!!!!!!!!!

Well, here it is, readers. *sigh* Sorry again for the delay. I've been busy on the road of life and high school. I've decided to clear up some misconceptions about some of the deadliest theropods (again....paleontologists classifcation for predatory dinosaurs) that ever lived......Dromaeosaurs or "Raptors." These started with Jurassic Park back in 1993. The confusion mainly was between Velociraptor mongoliensis and Deinonychus.

Commonly confused Dromaeosaurs (Part One of Movie Myths):




Velociraptor mongoliensis

Time Period: Late Cretaceous (70 million years ago-65 million years ago)

Diet: Carnivore

Method of kill: retractable "killing claw"

Height: 3 feet tall
Length: 6 feet long?
Locality: Gobi Desert in what is now Mongolia and China

Cool Facts: Cool fossil of it locked in combat with a Protoceratops near a protoceratops nest in Mongolia. Theorized as a pack hunter.



Deinonychus
Time Period: Early Cretaceous to Late Cretaceous (145-65 million years ago)
Diet: Carnivore
Height: 6 feet or as tall as a full-grown Human male.
Length: (I'm not sure how long it was)
Locality: North America
Method of kill: retractable "killing claw" (for lack of a better term.)
Cool Facts: Mistakenly called "Velociraptor" by fans because it was needed to fill the role of a 6-foot-tall "Raptor." They knew the difference thanks to Horner but, in Crichton's novel, the Velociraptors were 6 feet tall. Theorized as a pack hunter because a group of them were found together next to their prey. This indicates that they died trying to take down the herbivore. The vertebrae in the tail were stiff and interlocked creating a stiff and strong counter-balance for running and jumping.

The other annoying bit of misinformation floating around because of JP is that people claim the raptors in it are "Utahraptors" which were discovered after the movie was made, thereby wavering any chance of them being Utahraptors.

True but, but Utahraptors were bigger than the one's in the film. The "raptors" in the film were man-sized clearly making them Deinonychs. Perhaps, they unwittingly used Utahraptors. In fact, I think the Deinonychs were a little enlarged proabably for scare factor.

Yep, Hollywood don't care about real size. They like the scary size.
