Turners Falls Formation

These include Antipus flexiloquus, which has been interpreted as belonging to a small quadrupedal reptile[1] or a pterosaur,[2] though it is most likely a crocodylomorph.

[3] The formation is thought to represent the distal zones of three alluvial fans flowing west into a semiarid rift valley formed by a Mesozoic graben.

[4] These deposits represent the first infilling of the lowland that would one day become the Connecticut River Valley.

[4] In addition to trace fossils, the Turners Falls Formation bears some of the most well-preserved specimens of armored mud balls in the world.
