Eutreptodactylus itaboraiensis Baird & Vickers-Rich

This enigmatic bird from the Late Paleocene of Brazil is known only from a single, broken tarsometatarsus, which, however, apparently can be assigned to the cuckoos.

I cannot say that much about this bird, it appears to have been quite large for a Paleocene bird species, and it may indeed have been a real cuckoo or it may have been something completely different.


A little (long overdue) update … since this species is now thought to be closely related to – or even included within the family Gracilitarsidae.

The bird in my reconstruction still is about 15 cm long, about one third larger than Gracilitarsus mirabilis Mayr, the sole known species of its genus.
