In the 1960s, however, the first evidence of dinosaurs in the upper latitudes was discovered off Norway. Fiorillo said that 100 million years ago, Alaska was a lot warmer than it is today.
Evidence suggests that all dinosaurs were egg-laying, and that nest-building was a trait shared by many dinosaurs, both avian and non-avian. While dinosaurs were ancestrally bipedal , many extinct groups included quadrupedal species, and some were able to shift between these stances.
A new study shows that fluffy dinosaurs actually existed and roamed the South Pole. Yes, you read that right — Fluffy dinosaurs. For the first time, scientists have found evidence that dinosaurs ...
Several researchers support the existence of Paleocene non-avian dinosaurs. Evidence of this existence is based on the discovery of dinosaur remains in the Hell Creek Formation up to 1.3 m (4.3 ft) above and 40,000 years later than the K–Pg boundary. [138]
These features make Archaeopteryx a clear candidate for a transitional fossil between dinosaurs and birds, [15] making it important in the study both of dinosaurs and of the origin of birds. The first complete specimen was announced in 1861, and ten more Archaeopteryx fossils have been found since then. Most of the eleven known fossils include ...
Beneath the snowy slopes lay a prehistoric surprise: an ecosystem that predates the dinosaurs, revealed by melting snow before being stumbled upon by a hiker in the Italian Alps.
A study on bone histology of Trialestes romeri, providing evidence of a rapid growth rate, is published by Ponce, Cerda & Desojo (2025). [4] A study on the biodiversity of thalattosuchians throughout their evolutionary history, attempting to identify factors driving thalattosuchian evolution, is published by Forêt et al. (2025). [5]
Researchers are now proposing a surprising location for the birthplace of dinosaurs, based on the locations of the currently oldest-known dinosaur fossils, the evolutionary relationships among ...
