The specimens listed on this page are all thin sections of Permian vertebrate fossils from the Lower
Permian of Oklahoma. Each specimen has been mounted on a glass slide and ground thin enough
for study with reflected or transmitted light. The internal details of the bone are clear to see. Each
slide is individually labelled with full geological data and the genus/species represented (where
known). A typical thin section measures around 3/4 to 1 inch long on a 1 x 3 inch glass slide. No
coverslips are used. The images show representative examples of each type.
