New archive of ancient human brains challenges misconceptions of soft tissue preservation

Science Daily - Paleontology - Wed, 03/20/2024 - 11:24
A new study has challenged previously held views that brain preservation in the archaeological record is extremely rare. The team compiled a new archive of preserved human brains, which highlighted that nervous tissues actually persist in much greater abundances than traditionally thought, assisted by conditions that prevent decay.

Tanks of the Triassic: New crocodile ancestor identified

Science Daily - Paleontology - Mon, 03/18/2024 - 15:45
Dinosaurs get all the glory. But aetosaurs, a heavily armored cousin of modern crocodiles, ruled the world before dinosaurs did. These tanks of the Triassic came in a variety of shapes and sizes before going extinct around 200 million years ago. Today, their fossils are found on every continent except Antarctica and Australia.

Plant-killing genetic technology could wipe out superweeds

New Scientist - Wed, 03/13/2024 - 05:00
A ‘gene drive’ that spreads through plant populations could be used to wipe out pests such as superweeds, or to help save species by making them resistant to heat or disease

Alaska dinosaur tracks reveal a lush, wet environment

Science Daily - Paleontology - Tue, 03/12/2024 - 21:10
A large find of dinosaur tracks and fossilized plants and tree stumps in far northwestern Alaska provides new information about the climate and movement of animals near the time when they began traveling between the Asian and North American continents roughly 100 million years ago.

Higher carnivorous dinosaur biodiversity of famous Kem Kem beds, Morocco

Science Daily - Paleontology - Tue, 03/12/2024 - 12:38
An international team of palaeontologists applied recently developed methods to measure theropod (carnivorous) dinosaur species diversity. The newly applied method uses both traditional phylogenetic analysis, discriminant analysis as well as machine learning.

New study reveals insight into which animals are most vulnerable to extinction due to climate change

Science Daily - Paleontology - Thu, 03/07/2024 - 15:51
In a new study, researchers have used the fossil record to better understand what factors make animals more vulnerable to extinction from climate change. The results could help to identify species most at risk today from human-driven climate change.
