Short-armed Dinosaurs and Convergence Fantasies
Way down Argentina way, paleontologists found themselves a new dinosaur, and named it Meraxes gigas after a critter in George R.R. Martin stories. They were cleaning and studying it for about ten years. The skeleton is said to be more complete than any others of this type. They were so thrilled, this thing was given its own genus.
M. gigas was like T. rex in body structure, including short arms and a big head. This bad boy was supposedly stomping around about twenty million Darwin years before T. rex lived. Interesting that tyrannosaurid fossils have not been discovered in the Southern Hemisphere.

Patagonia is a long way from Montana. In 2012, researchers discovered a large theropod dinosaur resembling a T rex in Patagonia, along with several sauropods. They’ve been excavating, cleaning and classifying it for a decade, deciding where and when it evolved into its niche in Darwin’s fallen tree (see 29 June 2022). Notably, this large predator had a big head, small arms, and strong hind limbs like its more famous lookalike. How did it get that way? Answer: Darwin Flubber did it!

Sorry, Dave, I'm afraid I can't do that. People will have to continue reading about appallingly bad science at "Dinosaur Convergence Loses Its Grasp."
