The adults showed a greater degree of skeletal fusion in the tarsometatarsus and tibiotarsus, and also more prominent muscle scars.

The holotype, a tarsometatarsus, was discovered in July 1916 by zoologist Harold Elmer Anthony in the cave Cueva Clara.
23.
It was initially described as the left tarsometatarsus of a non-avian theropod by Brett-Surman and Paul in 1985.
24.
These small ornithopod dinosaurs were entirely unbirdlike, except for their ornithischian pelvis and a tarsometatarsus strongly convergent to that of Enantiornithes.
25.
However, the tarsometatarsus of the Puerto Rican quail-dove is longer than in the grey-fronted quail-dove.
26.
The metatarsals of the foot were relatively short and fused to each other and to the lower ankle bones, forming a tarsometatarsus.
27.
The large and stout tarsometatarsus shows that it might have been the largest known taxon within the genus " Dryolimnas ".
28.
It is only known from a sternum; a tarsometatarsus assigned to it actually belongs to the paleognath " Lithornis vulturinus ".
29.
As in other specimens, this supports an incipient tarsometatarsus in " Archaeopteryx ", approaching the fully fused condition in modern birds.
30.
A tibiotarsus is absent, unusual considering Chatterjee's claims for the pygostylian affinity of " Protoavis ", as is a tarsometatarsus.
