Fossil Trackway of Batrachopus

Bruce Museum Collection 2020.10.03

This block of mudstone formed along the shores of a rift lake during the Jurassic Period. It captures a moment in time, with raindrops and trackways of a small quadrupedal animal preserved as the soft sediments later hardened into rock. The footprints are identified to the ichnotaxon (trace fossil maker) Batrachopus, believed to have an early terrestrial crocodilian. This block, collected in Portland Connecticut, is unusual in that the surface was bears deep ripples. The specimen was donated by Mark R. Agostini Jr.
