A. antecedens

Last dinosaur done! This series was very fun to make, hope you all enjoyed :^D.

Alexornis antecedens is the only known species of its genus, it lived in the late Cretaceous and was discovered in the same formation as Labocania anomala.
It’s known from a fragmentary skeleton including bones from its shoulder, wing and legs. It’s one of the only birds in its class that coexisted with other non-avian dinosaurs, belonging to the group Enantiornithes, which included some of the most “advanced” birds for the period.
It’s estimated its size was similar to that of a sparrow. Its name comes from ornithologist Alexander Wetmore and the Greek word “ornis” (bird), and “antecedens” being Latin for “ancestral”.
Famously, this species was included in the animated movie Walking with Dinosaurs (2013), interpreted by John Leguizamo. Curiously, the animal is given a latino accent, as it refers to its Mexican origin while the movie is set in present day Alaska.
