Fossil Turtle Bones & Crocodilian Tooth - Aguja Formation, Texas

This is a really cool association of several fossils still in situ from the Aguja Formation of Texas. The largest bone of the piece is a partial limb bone of a turtle. Right next to it is a .65" long tooth of a crocodilian and there are numerous other bone fragments present in the rock. The entire piece measures 5.3 x 3.6" and comes with an acrylic display stand.

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 the borders of Big Bend National Park or in Mexico, where laws prevent collection of fossils for sale. One of our partners was lucky enough to purchase several hundred acres of ranch land in Texas containing a good exposure of these formations.

These formations are equivalent age to the Judith River Formations in the Northern US and Alberta, Canada. Because relatively little collecting has been done on these formations in Texas, most of the species remain undescribed. Our partner has been putting important material into research collections and working with museums and researchers, so in the coming years their work will help lead to formal descriptions for these dinosaurs.
