This is a 2.8" wide fossil unidentified crocodile bone section from the Aguja Formation, Brewster County, Texas. It is in excellent condition. Due to the lack of diagnostic markers, definitive identification is difficult. It is likely, this is the quadratojugal bone from the rear of the skull. This is the bone in the skull that engages the lower jaw forming the joint. The Aguja Formation has a number of undescribed crocodylimorphs and one bone section is often, not enough to identify one.
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.
