Researchers reporting in Current Biology on Oct. 18 have described a remarkable new species of fish that lived in the sea about 150 million years ago in the time of the dinosaurs. The new species of bony fish had teeth like a piranha, which the researchers suggest they used as piranhas do: to bite off chunks of flesh from other fish.
Planktonic foraminifera -- tiny, shelled organisms that float in the sea -- left behind one of the most complete fossil records of evolutionary history in deep sea deposits. Consequently, evolutionists have a relatively sturdy grasp on when and how new lineages arose. However, a study publishing Oct. 17 in the journal iScience reveals that one lineage evolved much more rapidly than everyone predicted, and researchers are looking beyond Darwin's original theories of gradual evolution to understand why.
Some 3,500 years ago, there was already a brisk trade in fish on the shores of the southeastern Mediterranean Sea. This conclusion follows from the analysis of 100 fish teeth that were found at various archeological sites in what is now Israel.
Researchers at the University of California, Riverside, have found the oldest clue yet of animal life, dating back at least 100 million years before the famous Cambrian explosion of animal fossils.
University of Cincinnati professor Takuya Konishi examined the youngest-ever specimen of tylosaur ever found. Like orcas, mosasaurs might have used their bony noses to strike prey.
Century-scale climate variability was enhanced when the Earth was warmer during the Last Interglacial period (129,000-116,000 years ago) compared to the current interglacial (the last 11,700 years), according to a new UCL-led study.
The smallest Tylosaurus mosasaur fossil ever found has been revealed in a new study in the Journal of Vertebrate Paleontology and surprisingly it lacks a trademark feature of the species.
A new, in-depth anatomical description of the best preserved specimens of a car-sized sauropod relative from North America could help paleontologists with unraveling the mystery of why some dinosaurs got so big.
New archaeological evidence from southwest Madagascar reveals that modern humans colonized the island thousands of years later than previously thought, according to a study published Oct. 10, 2018 in the open-access journal PLOS ONE by Atholl Anderson from the Australian National University, Canberra, Australia, and colleagues.
The oldest flying squirrel fossil ever found has unearthed new insight on the origin and evolution of these airborne animals.
