Megapezia footprints. Specimen of fossilised animal footprints preserved in rock. Fossil footprints have their own taxonomy, as it is not usually possibly to definitively link them to a specific animal. These ones are classified as Megapezia, and are thought to have been made by an early amphibian ancestor or tetrapod, such as an edopoid or an eryopoid-type temnospondyl. This specimen was obtained in 1977, from the rocks of the Hardraw Scaur (Yoredale series), Yorkshire, UK. It dates from around 340 million years ago, during the Carboniferous.
