Perhaps Cynodontipus-type burrows were made by a variety of tetrapods and represent plesiomorphic digging behaviour at the level of Amniota, using synapomorphybased trace-maker identification (Olsen 1995a; Carrano and Wilson 2001).
Similarities occur in the initial development stages of the copulatory organs in reptiles and mammals, which suggests that the standard of differentiation of a single penis is a basal trait in Amniota (REINAND; PIEAU, 1998 apud RIEPPEL, 2000).
For the analysis, Rieppel and deBraga compiled an extensive data matrix for amniota (reptiles, birds, and mammals) that included 33 amniote groups and 168 characteristics of their bones -- an important physical characteristic in defining clades.
