12.3" Fossil Theropod (Troodon?) Ilium - Montana

Fossil Theropod (Troodon?) Ilium - Montana #113083

This is a very interesting, 12.3" wide theropod Ilium from the Judith River Formation of Montana. We've shown it to several people familiar with the Judith River Formation; in their opinion it's likely from a large Troodon or possibly a yet to be identified theropod. It's too large to be from any of the other known raptors in the formation. It could possibly be from a juvenile Albertosaurus but in their opinion it didn't look robust enough.

It is in excellent condition with only some minor repair and crack fill work. It comes with a custom metal display stand.

The Judith River Formation is one of the world's most prolific sources of Late Cretaceous vertebrate fossils. At least sixteen Orders containing more than forty Genera are known from the formation. These include fish, amphibians, mammals, and insects in addition to reptiles and avian (birds) and non-avian dinosaurs. Among the more interesting specimens is Leonardo, a mummified and fossilized Brachylophosaurus. This is a hadrosaur, a duck-billed dinosaur found with amazing soft-tissue preservation: skin impressions can be found on 90 percent of its body! The pattern in the skin on its feet is even preserved. In addition to Leonardo, the Judith River Formation contains the remains of the theropod Hesperornis, the only known freshwater Hespernorthid, a penguin-like bird.
