New Dinosaurs Discovered in 2022

Jan. 05, 2023

In 2022 paleontologists identified spectacular giant herbivores, stubby-armed carnivores and more. Here, take a look at some of the new dinosaurs discovered in 2022.

Dinosaur fossils

1. Perijasaurus lapaz

In August, paleontologists announced the unearthing of a new, nearly 40-foot-long sauropod in Colombia, based on a well-preserved fossilized vertebra. This medium-sized dino would have roamed tropical lowland forested areas during the early- to mid-Jurassic, about 175 million years ago, according to the researchers' descr1ption.

2. Meraxes giga

Paleontologists logged another short-limbed carnivore in Northern Patagonia. From tail to snout, Meraxes giga is thought to have measured around 36 feet long and to have weighed nearly 9,000 pounds. Also dating from the Cretaceous, this member of the Carcharodontosauridae family had stunted arms like the infamous T. rex. (But that didn’t prevent it from chowing down on large herbivores.)

Thanks to this specimen’s almost complete skeleton, paleontologists are learning much more about Carcharodontosaurid feet and forearms, as well as the group's evolution. This group’s facial features, for example — including small horns and crests — were probably meant to attract mates.

3. Guemesia ochoai

Paelontologists in Argentina unearthed a partially complete skull belonging to a stubby-armed abelisaurid. Many of these “armless” dinosaurs possessed even smaller forelimbs than the infamously short-handed Tyrannosaurus rex. It would have roamed during the Late Cretaceous.

Researchers found the skull in the Los Blaquitos Formation in the Northwest of Argentina, though most of the country’s existing abelisaurids have been uncovered in the South, in Patagonia. The new species of carnivore is also smaller than others of its kind, such as the Carnotaurus, according to the paleontologists who made the discovery. In fact, it’s one of the smallest abelisaurids discovered so far.

4. Tuebingosaurus maierfritzorum

Sometimes a new dinosaur is right under your nose … or in the case of paleontologists in Germany, it is stocked in a university collection. Reexamining fossils held by the University of Tübingen, researchers announced the discovery of the herbivorous Tuebingosaurus maierfritzorum.

5. Jakapil kaniukara

The bipedal Jakapil kaniukara is a newly described small, armored dinosaur also discovered in Argentina. Dating from the Cretaceous, the approximately 5-foot-long Jakapil sported bony armor on its neck and back; its discovery makes it the first armored dinosaur from this period to be discovered in South America. The species belongs to the thyreophoran group, which includes other, more famous, juggernauts such as stegosaurus and ankylosaurus.

6. Mbiresaurus raathi

Researchers discovered an early ancestor of the towering and lumbering sauropods — a group that includes giants such as the brachiosaurus — in Zimbabwe. Mbiresaurus raathi, however, was a smaller and quicker omnivore. Measuring at around five meters long, it belongs to the sauropodomorph family that gave rise to giant and better-known dinosaurs such as Diplodocus. It takes the title of earliest known dinosaur found in Africa so far, dating back around 230 million years to the late Triassic.
