Diagnosis
Reference | Diagnosis | |
---|---|---|
G. Niedzwiedzki and T. Ptaszynski 2007 | Large, morphologically typical Synaptichnium with pes imprint up to 30 cm long. Pes digit proportions: IV>III>II>I (IV and III of similar length). Low value of the cross axis angle: 70°. Digit V relatively long and narrow. Manus imprints are 1.5 times smaller than pes ones (in the material studied the former are usually poorly preserved). |
