    Palaeocast Art Competition 2015

    After the success of last year’s palaeoart competition we’re stepping up a gear and launching an even bigger and better contest. This time we've got three times as many prizes to give away courtesy of Cider Mill Press, Palaeoplushies and Paleocreations. We're running the competition on Facebook and Twitter between the 1st May and 1st June using #palaeocastart.

    Episode 43: Ancient DNA

    DNA (deoxyribonucleic acid) is a molecule that encodes the genetic information within every species of life on earth. The information contained within the sequence of base pairs determines how any given organism develops and biologically functions. DNA is not just limited to the biological world, but is also now being utilised in palaeontology. But why is DNA not normally preserved? What's the oldest DNA we can recover? And what can we learn about fossil animals from their DNA? We spoke to ancient DNA expert Dr Ross Barnett in order to get answers.

    Episode 42: Pterosaur aerodynamics

    Palaeontology is more than just going out into the field, digging up bones, and putting them back together. A good understanding of biology, geology, and even engineering can help to figure out how extinct animals lived and especially how they moved around. To further comprehend how we can use knowledge of engineering in palaeontology, especially with respect to understanding extinct animal flight, we spoke to Colin Palmer from the University of Bristol, and the University of Southampton. His background in engineering provides a unique set of skills and angle to studying pterosaur flight.

    Episode 41b: Insects

    Insects are the most abundant and diverse group on animals on the planet today. Would they therefore also be expected to have the richest fossil record? When did they first evolve and how rapid was their diversification? Do we give enough attention to the evolution of insects? To get answers we spoke to Dr. David Penney, honorary lecturer at the University of Manchester and founder of Siri Scientific Press. Dr. Penney has just recently published an overview of palaeoentomology entitled 'Fossil Insects'.

    Episode 40b: Brachiopods

    Brachiopods are some of the most common fossils to be found in rocks worldwide. Their thick, hard and (often) calcareous shells make them preferentially preserved in the fossil record. We probably all have found one, but how many of us overlooked them at the time? What can a brachiopod tell us? How big a role have they played throughout geological time? In this second part of a two-part episode we continue our interview with Prof. Lars Holmer, University Uppsala, Sweden, all about the humble brachiopod.

    Episode 39: Dinosaurs of Alberta

    Alberta, Canada is one of the world’s richest areas for dinosaur fossils, and especially fossils from the Late Cretaceous. Iconic dinosaurs like T. rex, Triceratops, and Parasaurolophus, as well as numerous other dinosaurs and fossils can all be found in this region.We had a chance to chat with Professor Phil Currie of the University of Alberta at the Society of Vertebrate Paleontology meeting where we talked about Alberta and why it is such a fantastic place for dinosaur fossils.

    Episode 38: Ceratopsians

    Ceratopsians are some of the most iconic dinosaurs that we recognise today including animals like Triceratops and Styracosaurus, with their big horns and frills. But is that what all 'horned dinosaurs' looked like? In fact, early ceratopsians were small and horn-less, sharing other characteristics with their larger, more derived relatives. At the The Society of Vertebrate Paleontology 2014 we met up with Dr. Andy Farke from the Raymond M. Alf Museum of Paleontology in California and discussed ceratopsian diversity and a new species he was involved with naming and describing.

    Episode 37: Theropods and birds

    Theropods are what we would classically recognise as the meat-eating dinosaurs of the Mesozoic Era. They are best known from genera such as Tyrannosaurus and Velociraptor but the group is much more diverse and includies herbivores, beaked and ostrich-like forms. It is however the link between theropods and birds that has long-caught the public's attention and perhaps represents one of the most scrutinised evolutionary transitions. As more dinosaurs are discovered with feathers, should we still be asking where the cut-off point is between the two groups and not if there should be a distinction? We caught up with Dr. Steve Brusatte, University of Edinburgh, at the Society of Vertebrate Paleontology meeting, who spoke to us about the relationship between theropods and birds.

    Society of Vertebrate Paleontology 2014 Day 4

    Welcome to our coverage of the Society of Vertebrate Paleontology annual conference held this year at the Estrel Hotel, Berlin, between the 5th and 9th November. We're delighted to be back at this event, which is doubtless the biggest dedicated vertebrate palaeontology conference in the world. As per our usual conference coverage, we’re aiming to produce daily multimedia reports to give you an indication of what it's like to attend such an event and also to bring you the latest news in the field.

    Episode 35: Ostracods

    Ostracods are tiny crustaceans (relatives of shrimps, crabs and water-fleas), distinguished by having a shell that is easily fossilised. As microfossils, by virtue of a long and rich fossil record, ostracods are extremely useful for determining the age of the sedimentary strata in which they are found, as well as providing clues to the nature of the environments and climates in which those deposits were formed. The first ostracods lived in shallow continental shelf seas during the early Ordovician period nearly 500 million years ago, later spreading and diversifying into deep oceanic as well as continental environments such as lakes and rivers. Today, as living organisms, they are globally widespread and diverse, inhabiting almost every kind of aquatic environment from the abyssal depths of the oceans to freshwater ponds.

    IPC4 Day 1

    Welcome to our coverage of the 4th International Palaeontological Congress (IPC4) from Mendoza, Argentina. The International Palaeontological Congress is a global meeting devoted to Palaeontology throughout the world. It convenes every four years under the aegis of the International Palaeontological Association. Following tree previous editions in Sydney (2002), Beijing (2006) and London (2010), it now comes to the American continent for the first time. This conference is one of the most important events on any palaeontologist's calendar and so draws in delegates from all corners of the globe. Over the next few days we're going to have a fantastic opportunity to hear about the latest research in the field with more of a focus on the Southern Hemisphere.
