A couple of terror birds,Llallwavis scagliai found the carcass of a dead Pliocene Caviomorph rodent on a river bank.
Llallawavis scagliai (Magnificent Bird of Scaglia) is a large extinct predator bird, the most complete fossil of a Phorusrhacid "terror bird" yet found. The fossil, discovered in 2010 in sediment among the cliffs above La Estafeta beach, contains the complete palate, complete trachea,skull, voice box, and eye bones. The new species was around four feet tall and lived in Argentina approximately 3.5 million years ago during the Pliocene Epoch. L. scagliai likely roamed in grassland and weighed around 1.2m tall and weigh 20kg. The joints separating the skulls bones were fused, unlike modern birds, and that may have helped it smash prey.(en.wikipedia.org/wiki/Llallawa…
As a rule of sexual dimorphism I painted the male bird with more brilliant saturated colors.I hope you like this birdies.
