A 90-million-year-old fossil discovery in Patagonia, Argentina, is reshaping how scientists understand dinosaur evolution. 🦖🔬
Fulbrighter Dr. Peter Makovicky of the
@UmnTwinCities worked with researchers in Patagonia to identify one of the most complete skeletons ever found of Alnashetri, a small, bird-like dinosaur from the Cretaceous Period. This discovery, recently published in
@Nature , is reshaping scientific understanding of one of the most enigmatic groups of theropods: the alvarezsaurs—an early branch of the lineage that produced iconic predators like Tyrannosaurus Rex as well as modern birds.
“Having a near complete and articulated animal is like finding a paleontological Rosetta Stone,” said Dr. Makovicky, who credits his Fulbright Scholar award for enabling the extended, on-site research in Argentina required for a breakthrough of this scale.
Now back in Minnesota, Dr. Makovicky uses the Alnashetri discovery to teach American students how science unfolds, from field discovery and fossil preparation to peer review and publication.
