Jurassic Middle
Toarcian Bajocian

Partial skeleton

The material includes elements of at least two individuals plus a remain of another, indeterminate vertebrate, and a posterior dorsal vertebra is designated as the lectotype of Amygdalodon. All of the sauropod material originally referred to this species represents very basal, non- neosauropodan eusauropods. Amygdalodon is the only South American evidence for a probable Early to early Middle Jurassic global dispersal of basal eusauropodan sauropods.
