macroevolution, specializing in the illustrator artwork service fossil record. After resuming the conversation, I looked around his room and tried to avoid making eye contact with him. He said exactly what my inner child wanted the paleontologist to say. Professor Wensel's bookshelf is piled high with layers of academic books and collections of dissertations, mixed with relics from a lost prehistoric world, in what looks like layers of fossilized sections. Among these prehistoric fossils, the most conspicuous is an ancient insect fossil, whose delicate wing texture and mottled color are still legible.
There is also the remains of a vampire squid with well-preserved black ink sacs that still contain melanin. There is also a strange ancient worm that is a close relative of the worms we find on coral reefs today. In the corner of the room was an antique wooden cabinet with drawers, which I expected to hold other interesting fossils of animals. The room feels like an exhibition hall between a museum and a library. Just a few feet away from me is the star exhibit of this fossil gallery, Parrotosaurus (psittacosaurus in Greek, meaning "parrot lizard"). A close relative of Triceratops, this adorable herbivorous little-billed dinosaur lived in the forests of what is now Asia about 133 million to 120 million years ago.
The fossil specimen I'm seeing now is world-famous, not because the fossil retains intact skin, with even recognizable striped patterns, or because of the distinctive tail of feathered, pointed edges. Neither is what made this dinosaur fossil famous, most notably the fact that the dinosaur retained an underbody part of its body that could be used by future humans to study the mystery of its reproduction (more on that later). Then I looked back and focused on our conversation. Wensel told me that there was a particularly exciting discovery in the Yixian Formation in Liaoning, a famous fossil site in China, where two full-feathered Tyrannosaurus rex
