Best areas for rewilding European bison

Science Daily - Paleontology - Tue, 12/12/2023 - 18:19
Simulations integrate historical records, fossils, and ancient DNA to reveal why the European bison nearly went extinct, and pinpoint optimal areas for conservation.   Since the near-extinction of the European bison, enormous conservation efforts have helped to restore wild populations, and its numbers are on the rise. However, the study authors argue that ensuring the species's long-term protection and recovery requires understanding why they nearly went extinct in the first place.    'Our study also suggests areas where rewilding attempts are most likely to be successful,' said lead author July Pilowsky, currently a disease ecologist at Cary Institute of Ecosystem Studies. Pilowsky completed the research while working on their PhD at University of Adelaide and University of Copenhagen.

This Japanese 'dragon' terrorized ancient seas

Science Daily - Paleontology - Tue, 12/12/2023 - 10:23
Researchers have described a Japanese mosasaur the size of a great white shark that terrorized Pacific seas 72 million years ago. The mosasaur was named for the place where it was found, Wakayama Prefecture. Researchers call it the Wakayama Soryu, which means blue dragon.

Molecular fossils shed light on ancient life

Science Daily - Paleontology - Thu, 12/07/2023 - 15:15
Paleontologists are getting a glimpse at life over a billion years in the past based on chemical traces in ancient rocks and the genetics of living animals. New research combines geology and genetics, showing how changes in the early Earth prompted a shift in how animals eat.

Study reshapes understanding of mass extinction in Late Devonian era

Science Daily - Paleontology - Thu, 12/07/2023 - 15:15
A recently published study puts forth a new theory that volcanic eruptions combined with widespread ocean detoxification pushed Earth's biology to a tipping point in the Late Devonian era, triggering a mass extinction.

It turns out, this fossil 'plant' is really a fossil baby turtle

Science Daily - Paleontology - Thu, 12/07/2023 - 15:08
Researchers re-examined a plant fossil found decades ago in Colombia and realized that it wasn't a plant at all: it's a fossilized baby turtle. It's a rare find, because juvenile turtles' shells are soft and often don't fossilize well.

Geoscientists map changes in atmospheric carbon dioxide over past 66 million years

Science Daily - Paleontology - Thu, 12/07/2023 - 15:04
An international consortium of geoscientists has reconstructed atmosphereric levels of carbon dioxide going back 66 million years using proxies in the geoloogical record. Today's concenteration, 420 parts per million, is higher than it's ever been in 14 million years.

More than a meteorite: New clues about the demise of dinosaurs

Science Daily - Paleontology - Mon, 12/04/2023 - 12:51
What wiped out the dinosaurs? A meteorite plummeting to Earth is only part of the story, a new study suggests. Climate change triggered by massive volcanic eruptions may have ultimately set the stage for the dinosaur extinction, challenging the traditional narrative that a meteorite alone delivered the final blow to the ancient giants.

Earliest-known fossil mosquito suggests males were bloodsuckers too

Science Daily - Paleontology - Mon, 12/04/2023 - 12:50
Researchers have found the earliest-known fossil mosquito in Lower Cretaceous amber from Lebanon. What's more, the well-preserved insects are two males of the same species with piercing mouthparts, suggesting they likely sucked blood. That's noteworthy because, among modern-day mosquitoes, only females are hematophagous, meaning that they use piercing mouthparts to feed on the blood of people and other animals.

Crocodile family tree mapped: New light shed on croc evolution

Science Daily - Paleontology - Mon, 12/04/2023 - 12:50
Around 250 million years ago, 700 species of reptiles closely related to the modern-day crocodile roamed the earth, now new research reveals how a complex interplay between climate change, species competition and habitat can help explain why just 23 species of crocodile survive today.
