Basic Dromaeosar Info
Dromaeosaurs, also called “raptors” were small, quick, feathered Theropods from
the Cretaceous. Their best-known characteristic was the “sickle” claw on
their inside toes. Dromaeosaurs gained popularity thanks to inaccurate
portrayals in Hollywood films. Supporters of dinosaur-bird evolution like
to use Dromaeosaurs to support the theory, which is still, believe it or not,
highly controversial. Some of the better-known Dromaeosaurid genra are
below.
Dromaeosaurus
Compared to its
close relatives, Dromaeosaurus had a heavily built skull, which was more
suited for the higher pressures required for crushing. It lived during the late
Cretaceous in North America and was about 6 feet long and 35
pounds.
Microraptor
Microraptor
was a very small Dromaeosaurid, measuring in at less than 3 feet long. It
lived during the late Cretaceous in Asia. Due to the remarkable
preservation of their remains, we now have more insight on the bird-dinosaur
relationship. Because it had small, relatively ineffective wings on its
arms and legs, some believe it would have been a tree-dweller, using its wings
to glide from tree-to-tree.
Utahraptor
Coming from the early Cretaceous of North America, Utahraptor was the
largest of the Dromaeosaurids. The largest known specimen would have been
about 23 feet long, with evidence of much larger individuals (about 36 feet
long). If Utahraptor did indeed get to 36 feet long, this would
have put it in the same physical size range of the average Allosaurus,
though Utahraptor would have been lighter, making for a faster, more
nimble predator (not to mention absolutely
fear-inducing).
Velociraptor
Velociraptor is the most famous of the Dromaeosaurids. It lived
during the late Cretaceous of Asia and was much smaller than portrayed in
popular films (less than 7 feet long and under 40 pounds). The most famous
Velociraptor specimen was discovered “fighting” a
Protoceratops.
