The use of vocalizations as a resource for communication is common among several groups of vertebrates: singing birds, croacking frogs, or barking dogs are some well-known examples.
Ostrich-like dinosaurs called ornithomimosaurs grew to enormous sizes in ancient eastern North America, according to a study published October 19, 2022 in the open-access journal PLOS ONE by Chinzorig Tsogtbaatar of the North Carolina Museum of Natural Sciences and colleagues.
Markings on ivory seized in Uganda in 2019 suggested that the tusks may have been taken from a stockpile of ivory kept, it was thought, strictly under lock and key by the government of Burundi.
SUE the T. rex is one of the most complete, best-preserved Tyrannosaurus rex specimens ever found. That level of preservation helps reveal details about SUE’s life.
Living sharks are often portrayed as the apex predators of the marine realm. Paleontologists have been able to identify fossils of their extinct ancestors that date back hundreds of millions of years to a time known as the Palaeozoic period.
A trove of fossils in China, unearthed in rock dating back some 436 million years, have revealed for the first time that the mysterious galeaspids, a jawless freshwater fish, possessed paired fins.
An international team of scientists, including from the Universities of Bristol and Oxford, and the Natural History Museum, have discovered that a well-preserved fossilised worm dating from 518-million-years-ago resembles the ancestor of three major groups of living animals.
Paleontologists have identified a new genus and species of algae called Protocodium sinense which predates the origin of land plants and modern animals and provides new insight into the early diversification of the plant kingdom.
Field school was ending in 20 minutes when Emma Puetz, a junior in geology at Missouri S&T, hiked into the Montana canyons to hunt fossils one last time before heading home to Rolla. She climbed up a steep hill covered with loose gravel in a promising area for fossils. Nothing. Disappointed, Puetz decided to head down the hill by a different path.
Nearly 66 million years ago, a large asteroid hit Earth and contributed to the global extinction of dinosaurs, leaving birds as their only living descendants.
Smithsonian researchers have discovered a new extinct species of lizard-like reptile that belongs to the same ancient lineage as New Zealand’s living tuatara.
A new research conducted by two paleontologists at the University of Malaga has just revealed that human evolution uniquely combines an increase in brain size with the acquisition of an increasingly juvenile cranial shape.
Researchers have run through near-perfect fossils of the World’s first gliding reptile with a fine-toothed comb and untangled hitherto unknown facets to discover it was a change in tree canopy which likely facilitated such flight in these creatures.
Research conducted with the help of a University at Albany anthropologist has revealed the cascading effects that humans have had on mammal declines and their food webs over the last 130,000 years, a new study in the journal Science shows.
A new analysis of a beaver anklebone fossil found in Montana suggests the evolution of semi-aquatic beavers may have occurred at least 7 million years earlier than previously thought, and happened in North America rather than Eurasia.
The reconstructed megadolon (Otodus megalodon) was 16 meters long and weighed over 61 tons. It was estimated that it could swim at around 1.4 meters per second, require over 98,000 kilo calories every day and have stomach volume of almost 10,000 liters.
An international team of researchers have discovered that a mysterious microscopic creature from which humans were thought to descend is part of a different family tree.
Large dinosaur predators, such as Tyrannosaurus rex, evolved different shapes of eye sockets to better deal with high bite forces, new research has shown.
Idaho National Laboratory researchers recently imaged several fossils using a powerful X-ray microscope. The 3D images will be used to create exhibits for Wyoming’s Fossil Butte National Monument and help experts gain insight into the origins of these and other relics.
Scientists have cracked an enduring mystery, discovering how sauropod dinosaurs – like Brontosaurus and Diplodocus – supported their gigantic bodies on land.
Lumbering through the forested wetlands of Bulgaria around six million years ago, a new species of panda has been uncovered by scientists who state it is currently the last known and “most evolved” European giant panda.
Butchering marks on the remains of two mammoths discovered in New Mexico show that humans lived in North America much earlier than previously thought. Credit: National Park Service.
An abandoned Caribbean colony unearthed centuries after it had been forgotten and a case of mistaken identity in the archaeological record have conspired to rewrite the history of a barrier island off the Virginia and Maryland coasts.
Trilobites- extinct marine arthropods that roamed the world’s oceans from about 520 million years ago until they went extinct 250 million years ago, at the end of the Permian period - may have grown in a similar fashion and reached ages that match those of extant crustaceans, a new study has found.
Scientists have discovered that multituberculates, an extinct group of mammals, reproduced using long gestation periods, like today's placental mammals. That calls into question a longstanding view that marsupials have a more "primitive" mode of reproduction and placentals a more "advanced" strategy.
About 201 million years ago, volcanic eruptions covered an area roughly the size of South America in lava as Pangaea started to split. The Earth was changed. In the years that followed, 40% of all four-legged land animals were wiped out in the End Triassic Extinction (ETE). The exact cause was unknown. However, researchers recently discovered that atmospheric changes as a result of the eruptions caused freezing temperatures at high latitudes. The land animals that survived had feathers or hair as insulation: large dinosaurs.
Researchers discover a new fossil that is closely related to other animals that made the transition to land, but with features more suited for swimming and life in the water.
A paper published in Science Bulletin, a multidisciplinary academic journal supervised by the Chinese Academy of Sciences and co-sponsored by the CAS and the National Natural Science Foundation of China, shows that Artificial Intelligence is a highly effective tool to know which species of extinct carnivores acted on the fossil bones found at paleontological sites.
From the beginning of the Ordovician, marine life began its great radiation, which was characterized by the rapid appearance of new orders, families, and genera, together with the replacement of existing groups.
ROM (Royal Ontario Museum) revealed new research based on a cache of fossils that contains the brain and nervous system of a half-billion-year-old marine predator from the Burgess Shale called Stanleycaris
An international team that includes a University of Minnesota Twin Cities researcher has discovered a new big, meat-eating dinosaur, dubbed Meraxes gigas, that provides clues about the evolution and anatomy of predatory dinosaurs such as the Carcharodontosaurus and Tyrannosaurus rex.
Researchers at University College Cork (UCC) and the Swedish Museum of Natural History examined the end-Permian mass extinction (252 million years ago) that eliminated almost every species on Earth, with entire ecosystems collapsing.
End-Permian extinction (EPE) is the greatest biotic crisis in Earth's history, eliminating more than 90% of species in the oceans and more than 70% of species on land.
A fossilized lower jaw has led an international team of palaeontologists, headed by Bastien Mennecart from the Natural History Museum Basel, to discover a new species of predator that once lived in Europe.
A group of researchers from CONICET and the University of Utah demonstrated that during the time of the first dinosaurs, variations in the diversity and abundance of the plant and vertebrate animal species cannot be related to the climatic changes recorded throughout its deposition, in contrast with previous hypotheses.
Research involving palaeontologists from the Universities of Portsmouth and Southampton has identified the remains of one of Europe’s largest ever land-based hunters: a dinosaur that measured over 10m long and lived around 125 million years ago.
