Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| R. M. Casamiquela 1964 | Impresiones correspondientes a un dinosaurio de talla muy pequeña, cuadréupedo y de pie funcionalmente tridáctilo. Ángulo de paso cercano al llano. Digitígrado. Los tres dedo del pie, anchos, de tamaño differente, escasamente los laterales entre sí y mayor el central; éste en su porción proximal situado en un plano superior con respecto a ellos. Acuminados. Ángulo interdigital subigual. La impresión de la mano amigdaloide, digitiforme, del tamaño de un dedo del pie, frecuentemente adosada por el lado externo a la impresión del pie (de lo que resulta una impresión pseudo-tetradáctila). Huella de cola no visibles. | |
| S. de Valais 2011 | Quadrupedal trackways with symmetric manus and pes impressions, with the manus impressions located medial to, and usually in contact with, the pes prints. Both manus and pes prints are longer than wide, with the pes nearly twice the size of the manus. Manus imprints are tridactyl or tetradactyl, have subparallel digit impressions, and are nearly rhomboid in outline, with the major axis almost parallel to the midline. Pes prints are tridactyl and display outward rotation from midline; digit impressions are robust and show low divarication angles. Digit III is the longest. Digital pads are absent. The trackway is relatively wide, with high pace angulation for both manus and pedes. |
