The Parasaurolophus' pipes: Modeling the dinosaur's crest to study its sound

Science Daily - Paleontology - Thu, 11/21/2024 - 15:54
Scientists have presented results on the acoustic characteristics of a physical model of the Parasaurolophus' crest. They created a physical setup made of tubes to represent a mathematical model that will allow researchers to discover what was happening acoustically inside the crest. The physical model, inspired by resonance chambers, was suspended by cotton threads and excited by a small speaker, and a microphone was used to collect frequency data.

Worm-like fossil is the oldest ancestor of spiders and crustaceans

New Scientist - Thu, 11/21/2024 - 13:41
Arthropods belong to an evolutionary branch – the ecdysozoa – that contains about half of all animal species, and the earliest fossil evidence of the group now dates back 550 million years

Brainwave experiment shows minke whales have ultrasonic hearing

New Scientist - Thu, 11/21/2024 - 13:00
In the first hearing test of live baleen whales, the animals detected much higher frequency sounds than expected, forcing researchers to reconsider how these mammals respond to predators – and humans

A sliver of lab-grown wood has been made from stem cells

New Scientist - Thu, 11/21/2024 - 09:30
Growing wood directly from stem cells could offer an alternative to cutting threatened hardwood trees, but it isn't clear if it has same properties as actual wood

Thanksgiving special: Dinosaur drumsticks and the story of the turkey trot

Science Daily - Paleontology - Wed, 11/20/2024 - 11:16
Wings may be the obvious choice when studying the connection between dinosaurs and birds, but a pair of paleontologists prefer drumsticks. That part of the leg, they say, is where fibular reduction among some dinosaurs tens of millions of years ago helped make it possible for peacocks to strut, penguins to waddle, and turkeys to trot.

The chilling sound of the Aztec death whistle

Science Daily - Fossils - Tue, 11/19/2024 - 12:29
The Aztec skull whistle produces a shrill, screaming sound. A study shows that these whistles have a disturbing effect on the human brain. The Aztecs may have deliberately used this effect in sacrificial rituals.

New fossil reveals the evolution of flying reptiles

Science Daily - Paleontology - Mon, 11/18/2024 - 11:52
A newly discovered pterosaur fossil is shedding light on the evolutionary journey of these ancient flying reptiles. This complete specimen, named Skiphosoura bavarica, provides crucial insights into how pterosaurs transitioned from early, smaller forms to the later, gigantic species. By analysing the unique features of Skiphosoura, paleontologists can now trace the step-by-step evolution of pterosaurs, including changes in head size, neck length, wing structure, and tail length. This groundbreaking discovery offers a clearer understanding of how these magnificent creatures soared through the prehistoric skies.

Tiny worm makes for big evolutionary discovery

Science Daily - Paleontology - Mon, 11/18/2024 - 11:52
The history of a major animal group, composed of millions of species of insects, arachnids, and nemotodes, has been elusive -- until now. A team has now identified the oldest known ecdysozoan in the fossil record and the only one from the Precambrian period.
