Shark and vertebrate fossils

3D Model

Many of the fossils found at Chaco are not in their original position (in situ). Instead, many shark teeth are found lying on the surface (in float). These teeth probably eroded from the upper Cliff House Sandstone formation where there are more shark teeth in situ. Bone and tooth fragments like these can lead to the discovery of more complete specimens that help us understand the ecology of the ancient landscape
