Jurassic Limusaurus China Paleontologist. - 4:15 PM, Jun. 24, 2009 |
| A new dinosaur called Limusaurus has been discovered in China, from the Jurassic period.
It has hands that are very similar to the structure of birds' hands.
The similarity is that bird's wings are made of the second and third finger of the hand.
This dinosaur has diminished front claws where the second and third finger are dominant.
Paleontologists are touting this as more definitive proof of the relationship to birds and dinosaurs.
All this is well, great, and it's kind-of beside the point.
Birds were well established by the late Jurassic, with Archaeopteryx.
All this change must have happened in the early Jurassic and even in the Triassic.
What's great about the Triassic is that we have all of the definitive forms of dinosaurs, pterosaurs,
ichthyosaurs, and others, so why not look for birds there as well?
If we only find dinosaurs, then perhaps birds are a Jurassic dawning. That's cool, too...
