About 80 million
years ago, this long and narrow skull filled with sharp teeth belonged
to a dinosaur that lived in the Gobi. This theropod gives important clues
about the evolution of birds. Since its large eyes faced forward,
it was easily able to zero in on its prey.
mammal was discovered at Ukhaa Tolgod. By studying its small skull
and skeleton, scientists figured out that Deltatheridium is closely
related to the opossum. If you look closely at its mouth, you'll see a
The top view
of this lizard's triangular head reveals its pebble-like skin texture.
Gobiderma is a relative of the poisonous Gila (HEE-luh) Monster that lives
today in the U.S. and Mexico.
||Baby Protoceratops skeleton
This dinosaur was
related to Triceratops, and had a parrot-like beak. This dinosaur
walked on four legs (you can see two), and was heavily built.
If this Protoceratops had grown to adulthood, it would have grown a bony
frill over its neck.
At first this
fossil skull might make you think, "Huh? What's that!?" But if you
look at it carefully, you can see its large eye socket in the center.
It's hard to tell, but its mouth is actually pointing to the right.
dinosaur lived in the Gobi about 80 million years ago. Can you spot its
If the entire skeleton of this specimen had been preserved, you would see
that its body was protected by body armor and a tail club.
Towards the end
of the Mesozoic Era, this nest contained more than a dozen dinosaur
eggs. One of the hatchlings apparently died before it left the nest.
You can see its skeleton on top of the nest. Scientists used the hatchling's
bones to help them figure out the nest belonged to a troodontid
This extinct rat-sized
mammal had large eyes - the better to hunt at night! Although
means "hidden hero," it's just a coincidence that this specimen's body
is mostly hidden in the rock. Can you spot the crease or line on the
top of its skull?
