New fossil provides clarity to the history of Alligatoridae
''From what we have, we are able to understand a little bit more about the evolutionary history of caimans and the alligatorid group, which includes alligators and caimans.'' (2021-01-15)

Spectacular fossil discovery:
A team led by Sebastian Stumpf from the University of Vienna describes an well-preserved skeleton of the ancient shark Asteracanthus. This rare fossil find comes from the famous Solnhofen limestones in Bavaria, which was formed in a tropical-subtropical lagoon landscape during the Late Jurassic, about 150 million years ago. The almost complete skeleton shows that Asteracanthus was two-and-a-half meters long, which makes this ancient shark one of the largest of its time. The study is published in Papers in Palaeontology.

New discovery sheds light on the mysterious family life of notorious sabre-toothed tiger
New research indicates adolescent offspring of the menacing sabre-toothed predator, Smilodon fatalis, were more momma's cubs than independent warriors. (2021-01-07)

The ABCs of species evolution
Almost four decades of research have led scientists at Japan's Institute for Integrated Cell-Material Sciences (iCeMS) to propose that a family of transporter proteins has played an important role in species evolution. One protein in particular, called ABCA1, was likely crucial for vertebrate evolution by helping regulate when signals involved in cell proliferation, differentiation and migration enter a cell. This process was necessary for vertebrates to develop into more complex organisms with sophisticated body structures. (2020-12-23)

The 'crazy beast' that lived among the dinosaurs
New research published today in the Journal of Vertebrate Paleontology describes a bizarre 66 million-year-old mammal that provides profound new insights into the evolutionary history of mammals from the southern supercontinent Gondwana - recognized today as Africa, South America, Australia, Antarctica, the Indian subcontinent, and the Arabian Peninsula.

Water-to-land transition in early tetrapods
The water-to-land transition is one of the most important major transitions in vertebrate evolution. However, there is still uncertainty about when the water-land transition took place and how terrestrial early tetrapods really were. A new paper in Nature addresses these questions and shows although these early tetrapods were still tied to water and had aquatic features, they also had adaptations that indicate some ability to move on land. (2020-11-25)

From fins to limbs and water to land
The study shows how and when the first groups of land explorers became better walkers than swimmers. The analysis spans the fin-to-limb transition and reconstructs the evolution of terrestrial movement in early tetrapods. (2020-11-25)

Vertebrate biodiversity- a glimmer of hope
A McGill University-led team of biologists found, in an article published today in Nature, that the picture of dramatically declining vertebrate populations of all kinds is driven by a small number of outlier populations whose numbers are dropping at extreme rates. Once these outliers are separated from the mix, a very different and far more hopeful picture of global biodiversity emerges. (2020-11-18)

Paleontologists uncover three new species of extinct walruses in Orange County
Millions of years ago, in the warm Pacific Ocean off the coast of Southern California, walrus species without tusks lived abundantly. But in a new study, Cal State Fullerton paleontologists have identified three new walrus species discovered in Orange County and one of the new species has ''semi-tusks'' -- or longer teeth. (2020-11-16)

New genome alignment tool empowers large-scale studies of vertebrate evolution
Three papers published November 11 in Nature present major advances in understanding the evolution of birds and mammals, made possible by new methods for comparing the genomes of hundreds of species. Researchers at the UC Santa Cruz Genomics Institute developed a powerful new genome alignment method that has made the new studies possible, including the largest genome alignment ever achieved of more than 600 vertebrate genomes. (2020-11-11)

Largest set of mammalian genomes reveals species at risk of extinction
An international team of researchers with the Zoonomia Project has released the whole genomes of more than 80 percent of all mammalian families, spanning almost 110 million years of evolution. The dataset, published in Nature, includes genomes from more than 120 species that were not previously sequenced, capturing mammalian diversity at an unprecedented scale. Zoonomia data have already helped researchers in another recent study to assess the risk of infection with SARS-CoV-2 across many species. (2020-11-11)

Antarctica yields oldest fossils of giant birds with 21-foot wingspans
Some of the largest birds in history, called pelagornithids, arose a few million years after the mass extinction that killed off the dinosaurs and patrolled the oceans with giant wingspans for some 60 million years. A team of paleontologists has found two fossils -- each from individual pelagornithids with wingspans of 20 feet or more -- that show this gigantism arose at least 50 million years ago and lasted at least 10 million years. (2020-10-27)

African crocodiles lived in Spain six million years ago
The crocodiles that inhabited the coasts of North Africa during the late Miocene period embarked on a journey to Europe across what is now the Mediterranean basin. This is confirmed by the analysis of the first fossils of the Crocodylus genus in the Iberian Peninsula, found in the Valencian site of Venta del Moro between 1995 and 2006, and which are now being described for the first time. (2020-10-22)

(2020-10-06)

Dinosaur feather study debunked
A new study published in ''Scientific Reports'' provides substantial evidence that the first fossil feather ever to be discovered does belong to the iconic bird-like dinosaur, Archaeopteryx. This debunks a recent theory that the fossil feather originated from a different species. (2020-09-30)

Family care? Healed injuries suggest social behavior in ancestral wolves
Wolves today live and hunt in packs, which helps them take down large prey. But when did this group behavior evolve? An international research team has reported specimens of an ancestral wolf, Canis chihliensis, from the Ice Age of north China (~1.3 million years ago), with debilitating injuries to the jaws and leg. The wolf survived these injuries long enough to heal, supporting the likelihood of food-sharing and family care in this early canine. (2020-09-24)

Fossil evidence of 'hibernation-like' state in 250-million-year-old Antarctic animal
University of Washington scientists report evidence of a hibernation-like state in Lystrosaurus, an animal that lived in Antarctica during the Early Triassic, some 250 million years ago. The fossils are the oldest evidence of a hibernation-like state in a vertebrate, and indicate that torpor -- a general term for hibernation and similar states in which animals temporarily lower their metabolic rate to get through a tough season -- arose in vertebrates even before mammals and dinosaurs evolved. (2020-08-27)

Evidence of hibernation-like state in Antarctic animal
