Name: Pseudobradypus sp.

Age: Pennsylvanian (Desmoinesian ~305 m.y.a.)

Location: Hartshorne Sandstone, McAlester Formation, Krebs Group , Haskell County, Keota, Oklahoma

Description: There are multiple tracks present on this plaque that are assigned to the Ichnotaxon Pseudobradypus. The trackmaker is thought to have been a small amphibian. Given the highly-varied directionality, they were most likely not all made at the same time. Notice that there is a pair of sinuous tail drag marks, indicative of the mode of locomotion of these amphibians. The sand was probably wet in the early morning, allowing it to take the impressions seen here, which then dried up and were preserved for over 300 million years. Given the other ichnofossils that have been found, the region is thought to have been a freshwater tidal-flat setting.
