Comparing canine brains using 3D-endocast modelling
Based on digital endocranial cast models the canine brain does not increase proportionally with body size. Researchers at ELTE Eötvös Loránd and Kaposvár University in Hungary reconstructed the surface morphology of 28 canine brains, including various dog breeds, wolves, coyotes, and jackals. The shortening of the facial skeleton greatly influences the ratio of certain brain regions, primarily the olfactory bulb and the frontal lobe. These changes might have profound implications for olfactory and problem-solving abilities. (2020-10-22)

Ancient bony fish forces rethink of how sharks evolved
Sharks' non-bony skeletons were thought to be the template before bony internal skeletons evolved, but a new fossil discovery suggests otherwise. (2020-09-07)

Previous investigations had identified which animals they were, but very little else was known about what lay inside the mummies. (2020-08-20)

Bird skull evolution slowed after the extinction of the dinosaurs
From emus to woodpeckers, modern birds show remarkable diversity in skull shape and size, often hypothesized to be the result of a sudden hastening of evolution following the mass extinction that killed their non-avian dinosaur cousins at the end of the Cretaceous 66 million years ago. But this is not the case according to a study by Ryan Nicholas Felice at University College London, publishing August 18, 2020 in the open-access journal PLOS Biology. (2020-08-18)

Fossil mystery solved: Super-long-necked reptiles lived in the ocean, not on land
By CT scanning crushed fossilized skulls and digitally reassembling them, and by examining the fossils' growth rings, scientists were able to describe a new species of prehistoric sea creature. Tanystropheus hydroides, named after mythology's hydra, was a twenty-foot-long animal with a ten-foot-long neck. (2020-08-06)

Long neck helped reptile hunt underwater
Its neck was three times as long as its torso, but had only 13 extremely elongated vertebrae: Tanystropheus, a bizarre giraffe-necked reptile which lived 242 million years ago, is a paleontological absurdity. A new study led by the University of Zurich has now shown that the creature lived in water and was surprisingly adaptable. (2020-08-06)

New study sheds light on evolution of hell ants from 100 million years ago
An international research team co-led by Prof. WANG Bo from the Nanjing Institute of Geology and Palaeontology (NIGPAS) of the Chinese Academy of Sciences has confirmed the special trap-jaw predation mechanism of hell ants, providing new insights into their evolution. (2020-08-06)

Between shark and ray: The evolutionary advantage of the sea angels
Angel sharks are sharks, but with their peculiarly flat body they rather resemble rays. An international research team led by Faviel A. López-Romero and Jürgen Kriwet of the Institute of Palaeontology has now investigated the origin of this body shape. The results illustrate how these sharks evolved into highly specialised, exclusively bottom-dwelling ambush predators and thus also contribute to a better understanding of their threat from environmental changes. The study is published in the journal Scientific Reports. (2020-08-04)

Palaeontology: Ancient African skull sheds light on American crocodile origins
The extinct African crocodile species Crocodylus checchiai may be closely related to American crocodile species alive today, according to a study published in Scientific Reports.
