Fossil dung reveals clues to dinosaur success story

Science Daily - Dinosaurs - Wed, 11/27/2024 - 12:55
Researchers have been able to identify undigested food remains, plants and prey in the fossilized feces of dinosaurs. These analyses of hundreds of samples provide clues about the role dinosaurs played in the ecosystem around 200 million years ago.

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

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.
