A festive flying reptile family reunion 150 million years in the making

Science Daily - Paleontology - Thu, 12/19/2024 - 14:24
A new study finds nearly 50 hidden relatives of Pterodactylus, the first pterosaur. Joined by its newly discovered relatives, Pterodactylus's 'family' now encompasses tiny flaplings, a host of teenagers, some mums and dads and even a few large old seniors. Fluorescing bones stimulated by powerful LED UV torches, revealed invisible details of the head, hands and feet of Pterodactylus.

Chart of life extended by nearly 1.5 billion years

Science Daily - Paleontology - Thu, 12/19/2024 - 14:16
Fossilized skeletons and shells clearly show how evolution and extinction unfolded over the past half a billion years, but a new analysis extends the chart of life to nearly 2 billion years ago. The chart shows the relative ups and downs in species counts, telling scientists about the origin, diversification, and extinction of ancient life. With this new study, the chart of life now includes life forms from the Proterozoic Eon, 2,500 million to 539 million years ago. Proterozoic life was generally smaller and squishier -- like sea sponges that didn't develop mineral skeletons -- and left fewer traces to fossilize in the first place.

Massive volcanic eruptions did not cause the extinction of dinosaurs

Science Daily - Paleontology - Wed, 12/18/2024 - 16:48
While volcanism caused a temporary cold period, the effects had already worn off thousands of years before the meteorite, the ultimate cause of the dinosaur extinction event, impacted.

Fossil predator is the oldest known animal with 'saber teeth'

Science Daily - Paleontology - Tue, 12/17/2024 - 12:13
Scientists have discovered the oldest known animal with saber teeth: a predator that lived 270 million years ago. This animal, from before the age of the dinosaurs, was a dog-like creature that was related to the ancestors of mammals.

Buried landforms reveal North Sea's ancient glacial past

Science Daily - Paleontology - Fri, 12/13/2024 - 13:06
Glaciologists used sound waves to reveal Ice Age landforms buried beneath almost 1 km of mud in the North Sea. The results suggest that the landforms were produced about 1 million years ago, when an ice sheet centered over Norway extended towards the British Isles.

Study sheds light on the origin of the genetic code

Science Daily - Fossils - Thu, 12/12/2024 - 18:02
Nearly all living organisms use the same genetic code, a complicated mechanism by which genetic information is translated into proteins, the building blocks of life. A new study suggests conventional wisdom about how the code evolved is likely flawed.

A new timeline for Neanderthal interbreeding with modern humans

Science Daily - Fossils - Thu, 12/12/2024 - 13:57
Neanderthal genes make up 1-2% of the genomes of non-Africans. Scientists analyzed the lengths of regions of Neanderthal DNA in 58 ancient Eurasian genomes of early modern humans and determined that the introgressed genes result from interbreeding between Homo sapiens and Neanderthals about 47,000 years ago, over a single, extended period of about 7,000 years. The findings help pin down dates for out-of-Africa migration and the dispersal of Homo sapiens.

Oldest modern human genomes sequenced

Science Daily - Fossils - Thu, 12/12/2024 - 13:57
Few genomes have been sequenced from early modern humans, who first arrived in Europe when the region was already inhabited by Neanderthals. An international team has now sequenced the oldest modern human genomes to date. The genomes were recovered from seven individuals who lived between 42,000 and 49,000 years ago in Ranis, Germany and Zlaty kun, Czechia. These genomes belonged to individuals who were part of a small, closely related human group that first split off from the population that left Africa around 50,000 years ago and later settled the rest of the world. Although they separated early, the Neanderthal DNA in their genomes traces back to an admixture event common to all people outside Africa, that the researchers date to around 45,000-49,000 years ago, much later than previously thought.
