… just having been described from the Early Cretaceous Crato Formation in Brazil.:

reconstruction in life-size, quite a small bird

This was a member of the Euornithes, which include all living birds, yet it does not belong to any of the living bird groups of course; it is the oldest member of that group known from South America (older ones were found in China).

The bird is known only from a single right foot that lacks some of its bones; the fossil also contains some feathers which indeed may belong to the bird. [1]
