Spain Unveils Europe’s Most Complete Stegosaur Skull, 150 Million Years Old

Paleontologists in Teruel, Spain uncovered the most complete stegosaur skull in Europe, dating to the Late Jurassic and attributed to Dacentrurus armatus. The fossil, found at the Están de Colón site in Riodeva, preserves key skull bones and a neck vertebra, offering unprecedented insight into stegosaur anatomy, feeding, and evolution. The discovery supports a new evolutionary grouping, Neostegosauria, and the site has yielded hundreds of fossils across growth stages, reshaping understanding of dinosaur diversity in the region.

Patagonia Discovery: 20-Meter Sauropod Upends South American Dinosaur Lineages

A newly identified long-necked sauropod from Patagonia, Bicharracosaurus dionidei, about 20 meters long and dating to the Late Jurassic, blends features of brachiosaurids and diplodocoid relatives, potentially marking the first Jurassic brachiosaurid from South America; found by a shepherd on his farm and now housed in Trelew, the discovery reshapes ideas about sauropod evolution and continental distribution.

Portugal Beach Unearths 150-Million-Year-Old Dinosaur Nest

Researchers on Portugal's Santa Cruz Beach uncovered a nest of at least ten Late Jurassic dinosaur eggs, exquisitely preserved in cliff sediment, with evidence suggesting most hatchlings may have emerged; CT scans are planned to study any embryonic material and the eggs' microstructure.

Ancient Giants: Unveiling the Enormous Pliosaurs and Sauropods of the Jurassic Era

Paleontologists from the University of Portsmouth have published a research paper suggesting that a pliosaur species, similar to Liopleurodon, could reach a length of 14.4 meters, twice the size of a killer whale. The discovery of four enormous vertebrates in an Oxfordshire museum has provided more reliable evidence for the size estimate. These pliosaurs, which lived in the Late Jurassic seas, had massive skulls with protruding teeth and were at the top of the marine food chain, likely preying on ichthyosaurs, plesiosaurs, and smaller marine crocodiles. The findings shed light on the existence of truly gigantic pliosaurs and may challenge previous size estimations.
