Violent Life of Monogenetic Volcanoes

A new study in the journal Geology is shedding light on the brief but violent lives of maar-diatreme volcanoes, which erupt when magma and water meet in an explosive marriage below the surface of Earth. Maar-diatremes belong to a family of volcanoes known as monogenetic volcanoes. These erupt just once before dying, though some eruptions last for […]

Flexibility along the Neck of the Neogene Terror Bird Andalgalornis steulleti (Aves Phorusrhacidae)

Neck length and neck posture are both relevant to give the appropriate position of the head during all kinds of behaviors . For activities such as mating or defense the neck has the ability to perform more complex movements  linked to the cervical morphology. The head centre of gravity over the feet is deeply correlated with the […]

Bizarre Species of Miniature Dinosaur Identified

Not every dinosaur grew up to be a mighty predator like Tyrannosaurus rex or a hulking vegan like Apatosaurus. A few stayed small, and some of the smallest dinosaurs that ever lived — tiny enough to nip at your heels — were among the first to spread across the planet more than 200 million years […]

The color of feathers on dinosaurs

The color of some feathers on dinosaurs and early birds has been identified for the first time, reports a paper published in Nature this week. The research found that the theropod dinosaur Sinosauropteryx had simple bristles – precursors of feathers – in alternate orange and white rings down its tail, and that the early bird Confuciusornis had […]

Origin Of Claws Seen In Fossil 390 Million Years Old

A missing link in the evolution of the front claw of living scorpions and horseshoe crabs was identified with the discovery of a 390 million-year-old fossil by researchers at Yale and the University of Bonn, Germany. The specimen, named Schinderhannes bartelsi, was found fossilized in slate from a quarry near Bundenbach in Germany, a site […]

A mysterious seed fern, Lepidopteris, discovered from the Upper Permian of China

Recently, a mysterious seed fern, Lepidopteris baodensis sp. nov., dating to more than 251 million years ago (Ma), was discovered at the Baijiagou of Baode, Shanxi, China, from the Upper Permian Sunjiagou Formation. This discovery completely changed the understanding of the stratigraphic distribution of the genus Lepidopteris in China and promoted the taxonomic study of late Paleozoic plants. Since […]

new species of raptor dinosaur Found By Students

A new species of dinosaur, a relative of the famousVelociraptor, has been discovered in Inner Mongolia by two PhD students. The exceptionally well preserved dinosaur, named Linheraptor exquisitus, is the first near complete skeleton of its kind to be found in the Gobi desert since 1972, and will help scientists work out the appearance of other […]

Can the morphology of fossil leaves tell us how early flowering plants grew?

Fossils and their surrounding matrix can provide insights into what our world looked like millions of years ago. Fossils of angiosperms, or flowering plants (which are the most common plants today), first appear in the fossil record about 140 million years ago. Based on the material in which these fossils are deposited, it is thought […]

Rare 95 million-year-old flying reptile Aetodactylus halli is new pterosaur genus, species

A 95 million-year-old fossilized jaw discovered in Texas has been identified as a new genus and species of flying reptile, Aetodactylus halli. Aetodactylus halli is a pterosaur, a group of flying reptiles commonly referred to as pterodactyls. The rare pterosaur – literally a winged lizard – is also one of the youngest members in the world of […]
