Palaeocambarus is an extinct genus of crayfish discovered in the Yixian Formation in China, with only a single species, P. licenti. It is one of the oldest known fossil crayfish.[1][2][3]
The genus Cricoidoscelosus is now considered to be a junior synonym.[1] It was initially believed to be Late Jurassic (Tithonian) in age,[3] but it is now confirmed to have been Early Cretaceous (Barremian-Aptian) in age.[2]
