The potential negative effect of "inconsistent" fossils could be greater with fewer calibration points, although the validity of the method proposed by Near & colleagues (Near & Sanderson, 2004; Near et al., 2005) has been questioned (Marshall, 2008; Parham & Irmis

In the Jurassic the tracks of non--dinosaurian reptiles are scarcely documented and tracks generically attributable to lizard-like reptiles are reported only in the Lower Jurassic of the United States (Irmis
