Diagnosis
ReferenceDiagnosis
J. Moreau et al. 2024Tridactyl, very small-sized tracks (L = 3-5 cm), longer than wide and with a long projection of the trace of digit III (L/D = 2.1 in average). L/W ratio quite variable (1.2-2.5). Well-defined, very thin, elongated and often separated impressions of digits. Impression of digit III longer than traces of digits II and IV. Trace of digit III often curved distally. Traces of digits III and IV quite similar in length. Bases of digits II and IV proximally located at the same height. Variable but low divarication angle II-IV (35° in average). Tiny, oval and well-marked phalangeal pads. Tiny marks of acuminate claws.
