19.5" Fossil Hadrosaur (Kritosaurus) Femur - Aguja Formation, Texas
This is a 19.5" fossil femur of a Hadrosaur (Kritosaurus) from the Aguja Formation, Brewster County Texas. It is in very good condition with repairs, fills and restoration one would expect to find on a specimen like this. There is wear at the terminal ends, especially at the ball. This femur is from the left leg of an adult individual. On its stand this is a striking display.
Hadrosaursare frequently referred to as duck-billed dinosaurs and are members of the ornithischian family Hadrosauridae They were fairly common herbivores which roamed Asia, Europe and North America during the Upper Cretaceous Period. Many species of hardrosaurs had distinct crests on their head, some of which had air filed chambers that may have produced a distinct sound. These crests may have been used for both audio and visual display purposes.
This specimen was collected within the past year on private deeded property in Brewster County, Texas. You won't see any other dinosaur material from the Aguja & Javelina Formations for sale because nearly all of the formation lies within the boundaries of a national park or in Mexico which can not be collected. One of our partners was lucky enough to purchase several hundred acres of ranch land in Texas containing a good exposure of these formations and we will be offering more material from the locality in the future.
