Is it a bird, is it a plane, is it a dinosaur?

Yep, that’s right, scientists have been studying the connection of today’s modern birds to their long-lost relatives, the dinosaurs. For many years, paleontologists believed that all dinosaurs were just giant lizard-like creatures.

Relatively recent discoveries in China have changed the minds of many scientists. This area of Northeastern China has attracted paleontologists to explore the lake and volcanic ash deposits abundant with ancient fossils. These fossils are bird-like in structure and lead to the newly held belief that many dinosaurs were feathered.

A local farmer dug in the rock and knew he had something special when he found the first fossil of Confuciusornis (sacred bird of Confucius). The fossil, about the size of a modern-day crow, had a beak and feathers with a long plumage tail. Since this discovery, more digging into the rocks in the region has unearthed other ancient flying dinosaurs, protopteryx, Sapeornis, and Yanornis. 

But these are not the only flying dinosaurs. Long before Confuciusornis, Archaeopteryx was dated to have lived 150 million-years-ago, and part of the Avialae clade. These are the closest relatives to modern birds. They had larger braincases, feathers, and pneumatic bones like today’s birds; but also had teeth, three-fingered hands and claws, and a long, stiffened tail like dinosaurs.

But when you ask a child about ancient creatures of the sky, most will answer with the pterodactyl. The pterodactyl is one type of Pterosaur that ranges in size from a fighter jet to a sparrow. With HUGE heads, long necks, heavy bones, and stiff skin-like wings, these flying lizards were terrifying carnivores to the dinosaurs living below.  

The Pterosaurs evolved significantly over time. They lived from 251 million years ago to 66 million years ago, and in that time, some species got larger, while others showed different ways they took off for flight. But the most baffling to many scientists is how they were able to hold up their giant heads. Paleontologists at the University of Illinois at Urbana-Champaign have recently had a breakthrough modeling how the vertebrae were arranged to create a strong structure.

We are excited to introduce a relatively new pterosaur to young readers this fall, the Hatzegopteryx. They were giants of the sky and believed to be a dominant predator in the area now known as Romania. The first fossil was found in 2002 in Transylvania. 

Timothy J. Bradley’s story, I am Hatzegopteryx follows a Hatzegopteryx from egg to extinction as he grows and learns to soar. Written in simple three-word sentences, even the smallest dinosaur enthusiast will be reading this book in no time.
