4.4" Tall Kritosaurus Vertebrae - Aguja Formation, Texas
This is a 4.4" tall, vertebrae from Kritosaurus navajovius. Kritosaurus is believed to be one of the largest genus of Hadrosaur, though little is known about it. It was collected from the Aguja Formation which has produced very little dinosaur material in the past.
The bone is very solid, but there is some restoration to end edge of each end where some erosion had occurred.
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 Formation for sale because nearly all of the formation lies the borders 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. The formation is the equivalent of the Judith River Formation in the Northern US/Canada.
These formations remain understudied, and many of the dinosaurs remain undescribed. Research collections are being put together from the locality and hopefully this material and the associated data will help shed more light on dinosaurs of West Texas in the future.
