It’s a bird! It’s a plane! It’s… a dinosaur? Nope to all of the above. This Fossil Friday, let’s talk about pterosaurs—the first animals with bones to evolve powered flight. Though they were related to dinosaurs, pterosaurs evolved on a separate branch of the reptile family tree. They ruled the skies for more than 150 million years, evolving into dozens of different species. Some were as small as a paper airplane while others, like Pteranodon pictured here in the Museum's Hall of Late Dinosaurs circa 1940-1960, had a wingspan of more than 20 ft (6 m).

Along with other large pterosaurs, Pteranodon longiceps was first discovered in western Kansas, near a chalk formation called Monument Rocks. Today the region is dry, but at the time this species lived, about 85 million years ago, central North America was covered by a seaway. This large pterosaur likely spent its days flying over the sea. Unlike early species of pterosaurs, Pteranodon and many other Cretaceous-era species didn’t have any teeth. In fact, its genus name means “winged and toothless,” while the second name, longiceps, means “long-headed.”

Today, you can find Pteranodon in the Hall of Vertebrate Origins. We're open daily from 10 am-5:30 pm! Plan your visit.

So the Tully Monster (Tullimonstrum gregarium) is an incredibly enigmatic extinct animal whose fossils have only been found in one section of the Mazon Creek Fossil Beds near Morris, Illinois. Dating back to around 309 million years ago during the Pennsylvanian Epoch of the Carboniferous Period, the ironstone concretions found here are particularly rich with fossils.

The Tully Monster has stymied paleontologists for decades, because no one's been entirely sure how to classify it. It doesn't resemble anything else that's been found there or elsewhere, and it didn't have any features that easily distinguished it as a vertebrate or invertebrate.

So this most recent study consisted of scientists painstakingly analyzing over 100 Tully Monster fossils, along with several dozen fossils of other species found in the same area. They were looking in particular for any traits that would suggest these were vertebrates. In short? They didn't find any. Which suggests that the Tully Monster was most likely just a very, very weird invertebrate--not so surprising given the wide diversity of aquatic invertebrates found today!

One thing the study didn't look into was the possibility that this species may have been something even more unusual--a non-vertebrate chordate. These animals have a notochord, a flexible structure that provides attachment for muscles similarly to a vertebrate's spine. While modern vertebrates may have a notochord during embryonic development, most do not retain it beyond a vestigial state once development is complete.

There will no doubt continue to be debate about just what the Tully Monster actually was, but this study adds a significant piece to the puzzle.

Happy Fossil Friday! With sharp teeth, long legs, and sickle claws, Deinonychus antirrhopus was likely a formidable predator. This dinosaur, which could reach lengths of about 7 ft (2.1 m) from nose to tail, lived during the Early Cretaceous, some 107 million years ago. It belonged to a group of dinosaurs called maniraptors, or “hand-robbers.” Its hands and feet were equipped with sharp claws for catching and grasping prey. Like modern-day birds, it had hollow bones.

Fun fact: The Deinonychus on display in the Museum is a real fossil skeleton—and the only one of its kind on display anywhere in the world! See it up close in the Hall of Saurischian Dinosaurs! We're open daily from 10 am-5:30 pm. Plan your visit.
