Velociraptors

Unlike the movie Jurassic park the Velociraptor is more like the size of a turkey, weighing up to 33 lbs and about 6 1/2 feet long which is mostly made up by their tail. There are larger versions like the Utahraptor. They rained mostly in the Asian lands near and in Mongolia.

The raptor pictured above lived on our planet approximately 71 to 75 million years ago.

Their arm's bone structure is much like that of the modern day bird. These dinosaurs had three fingered claws with the middle one the longest (2.6 inches long).

Orkoraptor Burkei

I know this video is a year old but its interesting that there still finding knew kinds of dinosaurs. Found in 2001 but it took 7 years to identify it as a knew specious. Named after the "toothed river"(Orkoraptor)and Coleman Burke (Burkei).

Archaeopteryx

Is there a link between dinosaurs and present-day birds. Here is a picture displaying this supposed half bird half dinosaur about 150 million-year-old ,called Archaeopteryx,(meaning "ancient wing") the first-known example of a feathered dinosaur?

Archaeopteryx had a wingspan of about 1.5 feet (0.5m) and about 1 foot or 30 cm from beak to tail. Weighing anywhere from 11 to 18 ounces or 300 to 500 grams.
It was about the size of a crow.

Tyrannosaurus Or Better Known as The T. Rex

Tyrannosaurus is believed to be one of the largest (40 feet long and 6-8 tons) carnivores of the dinosaurs area living from 63 million years ago to 60 million years ago. The largest known skulls of a T. Rex measured 5 feet (1.5 m) in length!

Here's an interesting video of the possible evolution of the T rex from the National Geographic Channel .
