This is a section of a Cretaceous Dinosaur Bone Chunk. These fragments were found while surface collecting in Cretaceous deposits of the Hell Creek Formation.
The Cretaceous Dinosaur Bone Chunk was found while prospecting sites within the Badlands of Montana. Because the badlands have little vegetation, when it rains, the rains wash away sediment. So when prospecting bone fragments as well as turtle shell, fish scales and other fossils are exposed. This fragment is a piece of genuine Dinosaur Bone from the Cretaceous Period. There are many bone fragments found while prospecting. When the bone is exposed to the elements it begins to decay. Because this decay is rapid, a dinosaur bone may fall into dust in just a few years. This bone is also called float because it “floats” downhill revealing a possible dinosaur bone bed.
Because of the intense sunlight any fossil expon the surface will begin to bleach white. Such is the case with this piece of Dinosaur bone. The normal color of Hell Creek fossil material is a dark brown color. This deposit is from the time of T-rexes and Triceratops dinosaurs. Many fossils have been found in the Hell Creek Formation and most are in exceptional condition. But any fossil on the surface that is exposed to harsh conditions will rapidly begin to decay.
This deposit has been known for many years and fossils such as this dinosaur bone are continuously being eroded to the surface. Because this bone was found during a surface collecting mission, they are well bleached. Because it was found in the general vicinity of a partial Triceratops bone bet, it is possible this is a piece of a Triceratops.
This was found in July of 2023 during a field prospecting mission.
