Skeletal time! Here's my new skeletal reconstruction of Kelenken guillermoi, one of the largest Phorusrhacids and one of my personal favorites. Weighing at 315 kgs, Kelenken was easily one of the largest predatory birds, and was the largest predator in its environment.

Inspiration for paleoart: In some bird species, females are more colorful than males, like these Greater painted-snipes

🚨NEW STUDY DROP🚨 Brand New Terror Bird from an Upper Pleistocene cave in Bahia, Brazil! Named, Eschatornis aterradora, it is described off just a single leg bone that reportedly has enough diagnostic traits to name a new species off of. It wasn't big! 🎨: Zeinner de Paula

The flock gets a new applicant but Red is unsure how "picking up the target and smashing them against a rock and poking holes in their skulls" will translate on a slingshot

Research on the melanosomes of terror birds reveal they were bright red, and had an appetite for pigs. “You didn’t want to be in this bird’s space when it was angry, it’s temper was truly epic.” Source: royalsocietypublishing.org/r…

Xenosmilus hodsonae feeding on Platygonus. Tooth marks on the fossil peccary bones show that sabertooths efficiently defleshed their kills. One of many new illustrations I created for the exhibition "Dientes de Sable".

Terror birds (Phorusrhacidae) ruled South America for ~40 Ma, but their growth was a mystery. New hindlimb osteohistology shows rapid, uninterrupted growth, heavy remodeling & cursorial stress in Oligocene Andrewsornis & Physornis. Dreyer et al.: anatomypubs.onlinelibrary.wi…

Andalgalornis steulleti, the only terror bird with that classically rectangular-looking head. Modified from Witmer Lab’s scan and the Field Museum mount, as well as Patagornis and Llallawavis! Scalebar = 1 meter.
Replying to @randompaleonerd
Do you have skeletal of Andalgalornis that is publically sharable?

Rough cranial multiview and reference for the terror bird Andalgalornis steulleti! Skulls are edited from Witmer Lab‘s skull scan photos and the Museo de La Plata’s sketchfab model of the skull! Figures on the right are taken from the doctoral thesis of Dr. Federico Degrange.

NOTE - The front-facing views are imperfectly edited and do not align fully with the lateral views since they are edited from screenshots of a 3D model! This reference is not 100% precise but is meant to serve as an artistic reference.

Ornimegalonyx oteroi skeletal, the not-long-legged owl. Many reconstructions portray it as a long-legged barn owl, but this isn’t the case. The animal had normal proportions to extant owls and was likely capable of minimal flight. The females of these owls were larger than males.

The classic terror bird, Phorusrhacos longissimus! Known fossil elements, including the limbs, vertebrae, and a new skull, suggest a shorter yet heavier and more robust animal, a top predator in its ecosystem alongside other Phorusrhacids. #paleoart
