Fossils from a 190-million-year-old nesting ground have revealed that its dinosaurs likely lived in herds. The species – Mussaurus patagonicus – are now the oldest known herding dinosaurs, according to a paper in Scientific Reports. “We’ve now observed and documented this earliest social behaviour in dinosaurs,” says Jahandar Ramezani, a researcher at the Massachusetts Institute … Continue reading Oldest known dinosaur herds found in Patagonia

The dinosaur in the coal mine
Fossil dinosaur footprints found 50 years ago in a Queensland coal mine – and long thought to belong to a massive Triassic carnivore – have been reanalysed, and found to belong to a large, docile herbivore, according to a new study out today in Historical Biology. The researchers, from the University of Queensland (UQ), were … Continue reading The dinosaur in the coal mine
Cretaceous crab revolution in exquisite detail
Picture the scene: you’re a crab minding your own business, scuttling along the shoreline on a balmy day when, out of nowhere, a blob of sticky tree sap encases you, freezing you in time for 100 million years. It was a moment of bad luck for this unfortunate crustacean, but a big win for science, … Continue reading Cretaceous crab revolution in exquisite detail
Tracing human origins by foot
A new study has pushed back the estimated age of 50 footprints preserved in rocks on the Mediterranean island of Crete – footprints that were already thought to be among the oldest pre-human prints in the world, and have now been dated to around 6.05 million years ago. The international team of researchers, whose study … Continue reading Tracing human origins by foot
What to do if you find fossils or artefacts
Six years ago, grazier Robert Hacon was driving around his cattle property in outback Queensland when he drove over what he thought was a cow skull. Past into present: A trilobite fossil, Redlichia rex found at Emu Bay, Kangaroo Island – a marine creature that lived over 500 million years ago during the Cambrian period.

Animal? Vegetable? Now mineral.
All other photos in this story by Ian Connellan. On a hillside just west of the Flinders Ranges, geologist Mary Droser lounges casually on a slab of 550-million-year-old sandstone. The sun has just hit its golden afternoon angle; it illuminates squiggled lines in the rocks, throwing into sharp contrast some of the earliest evidence for … Continue reading Animal? Vegetable? Now mineral.
Bone idle: distressed palaeontologists call for a halt to fossil digs
Happy Fossil Day from Cosmos! Palaeontologists simply can’t stop finding fossils, and leading researchers say it’s beginning to get concerning. “We have museums bursting at the seams with specimens – every day we’re rediscovering and reclassifying species we collected centuries ago,” says Associate Professor Trevor ‘Tee’ Wrecks, a palaeontologist from the State Museum of Eastern … Continue reading Bone idle: distressed palaeontologists call for a halt to fossil digs

Can we really extract ancient DNA from dinosaurs?
From million-year-old dinosaur remains to ‘resurrecting’ mammoths, stories in the news about ancient DNA make it seem as though Jurassic Park is just around the corner. But ancient DNA is also an important tool for viewing the past. The only problem is that it’s not quite as abundant or easy to use as some think. … Continue reading Can we really extract ancient DNA from dinosaurs?
New species of ancient tardigrade found preserved in amber
A brand-new species of ancient tardigrade has been discovered in 16-million-year-old Dominican amber. The newly found fossil, described in Proceedings of the Royal Society, dates back to the Miocene epoch, looks like a modern-day tardigrade, and represents a whole new genus and species: Paradoryphoribius chronocaribbeus (aka beusty boi). This is only the third tardigrade amber … Continue reading New species of ancient tardigrade found preserved in amber
Decoding the secrets of a forgotten human history during the Pleistocene
An international team of researchers has discovered the first fossilised bone from a Pleistocene-era human in Wallacea, the cluster of Indonesian islands, including Lombok, Sulaewsi, Timor and Sumba, that were the likely seafaring gateway for the first humans to populate Australia. The new find, published today in the journal PLOS one, offers a tantalising glimpse … Continue reading Decoding the secrets of a forgotten human history during the Pleistocene
Meet the new dinosaur: Horned, crocodile-faced hell heron
British palaeontologists have unearthed two new species of dinosaur on the unassuming, 380 square kilometre Isle of Wight, off England’s south coast, according to a new study out today in the journal Scientific Reports. The two new creatures appear to be types of spinosaurids, predatory theropod dinosaurs related to the giant Spinosaurus. The haul of … Continue reading Meet the new dinosaur: Horned, crocodile-faced hell heron
