The evolution of photosynthesis better documented thanks to the discovery of the oldest thylakoids in fossil cyanobacteria

Science Daily - Paleontology - Fri, 01/05/2024 - 13:50
Researchers have identified microstructures in fossil cells that are 1.75 billion years old. These structures, called thylakoid membranes, are the oldest ever discovered. They push back the fossil record of thylakoids by 1.2 billion years and provide new information on the evolution of cyanobacteria which played a crucial role in the accumulation of oxygen on the early Earth.

'Giant' predator worms more than half a billion years old discovered in North Greenland

Science Daily - Paleontology - Wed, 01/03/2024 - 14:42
Fossils of a new group of animal predators have been located in the Early Cambrian Sirius Passet fossil locality in North Greenland. These large worms may be some of the earliest carnivorous animals to have colonized the water column more than 518 million years ago, revealing a past dynasty of predators that scientists didn't know existed.

Sharks can be deterred from beaches by catching and releasing them

New Scientist - Wed, 01/03/2024 - 06:44
A non-lethal method of catching great white sharks and releasing them 500 metres further out to sea can make the predators steer clear of beaches where people swim

'Juvenile T. rex' fossils are a distinct species of small tyrannosaur

Science Daily - Paleontology - Tue, 01/02/2024 - 18:09
A new analysis of fossils believed to be juveniles of T. rex now shows they were adults of a small tyrannosaur, with narrower jaws, longer legs, and bigger arms than T. rex. The species, Nanotyrannus lancensis, was first named decades ago but later reinterpreted as a young T. rex. The new study shows Nanotyrannus was a smaller, longer-armed relative of T. rex, with a narrower snout.

Unveiling ancient secrets: 3D preservation of trilobite soft tissues sheds light on convergent evolution of defensive enrollment

Science Daily - Paleontology - Thu, 12/21/2023 - 00:28
Researchers describe unusual trilobite fossils prepared as thin sections showing the 3D soft tissues during enrollment. The study reveals the soft undersides of enrolled trilobites and the evolutionary mechanism that allows arthropods to enroll their bodies for protection from predators and adverse environmental conditions.

Mysterious fruit shown to be the oldest known fossils of the Frankincense and Myrrh family

Science Daily - Paleontology - Tue, 12/19/2023 - 11:44
Early in the 1970s, paleontologists discovered strange fossilized fruits between hardened rock from one of the largest volcanic eruptions in Earth's history. The identity of these fossils remained elusive for the next several decades. Using CT scanning, scientists have now determined they are the oldest fossils from species in the Frankincense and Myrrh family.
