1.65" Tyrannosaur (Undescribed) Tooth In Situ - Aguja Formation, Texas

Tyrannosaur (Undescribed) Tooth In Situ - Aguja Formation, Texas #88856

This is a beautifully preserved, 1.65" long tooth of an undescribed Tyrannosaur from the Aguja Formation of Texas. It was left in situ in a good sized chunk of rock full of other bone fragments. The tooth has wonderful enamel preservation, great serrations and some interesting feeding wear to the tip. There is a crack running through it which has been stabilized along with the rest of the rock.

Comes with a 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.
