Palaeocast

Mongolia is a vast country with fossils from almost every period in the history of life. Important specimens representing the origin of birds, the origin of mammals, many unique dinosaur species, and the first dinosaur eggs to be identified, have all been found within it's borders. For this reason it has long been the focus of field expeditions by Mongolian and international academics, but the rem...

Players will have the opportunity to take control of several different species of dinosaur in their natural environment. You will attempt to survive from hatchling to adult, mana...

Around 250 million years ago, the largest biotic crisis the world has ever known occurred. The Permo-Triassic Mass Extinction (PTME) was an event that saw the loss of up to 95% of all species. The extinction forever changed the face of life on this planet, but what caused it? How long did the PTME last? Who were the big winners and losers? And how long did it take for life to recover? Prof. Mike B...

Science is a process and so the door to the revision and refinement of hypotheses must always be left open. From the research discussed in our  last episode , the newspapers would have you believe that the mystery of the Tully Monster had been solved once and for all. Yet only a couple of weeks later, another new study has weighed in on the identity of this enigmatic fossil. This episode is releas...

Tullimonstrum gregarium , better known as the ‘Tully Monster’ is a problematic fossil from the Late Carboniferous Mazon Creek lagerstätte, Illinois, USA. The identity of this fossil has been the subject of much debate, due to its peculiar form. Several competing hypotheses have placed it within the arthropods, fish, worms or even molluscs.   Joining us in this interview is Dr Victoria McCoy whose...

Dr. Larry Witmer’s lab at Ohio University studies the anatomy of modern animals to make interpretations regarding the functional morphology of extinct vertebrates. WitmerLab incorporates anatomical studies with cutting-edge technology, allowing for the reconstructions of soft-tissue structures no longer present in fossils (including respiratory apparatuses, brains, and inner ears). These reconstru...

Diet is perhaps the most important aspect of ecology. As such, understanding the diet of extinct animals is crucial if we wish to reconstruct the ecosystems of the past. However, determining what was on the menu for extinct animals, known only from fragmentary fossils, is far from straight forward. We spoke to Dr David Button, from the University of Birmingham, to learn about the techniques palaeo...

Beneath the city of Chemnitz, Germany, exists a entire fossilised forest. This whole ecosystem was preserved in life-position during a series of volcanic events. The forest is from the Permian period and thus represents a fantastic snapshot of life during a period where terrestrial fossils are notoriously rare. Joining us to discuss the flora and fauna of the Permian of Germany is Dr Ronny Rößler,...

One of the most difficult aspects of palaeontology is understanding how extinct animals moved around. It’s one thing to find a fossil and reconstruct it’s morphology, but it’s completely another to put that morphology into action and understand the locomotion or behaviour. One reason for this is because of the lack of soft tissue and muscles. The field of biomechanics can help with this by looking...

The Wealden Supergroup of southern England is known for it's Cretaceous fossils, particularly of dinosaurs, but also crocodilians, pterosaurs, lizards, invertebrates, and plants. The group represents the Early Cretaceous, and is well known for showing us the environment of this time period, which is not well-represented in many other places in the world. It has been essential in helping to underst...

Laura interviews Dave about Palaeocast's new project: The Virtual Natural History Museum. The Virtual Natural History Museum (V-NHM) is a project designed to make digital palaeontological resources accessible like never before. This website will integrate fossil multimedia from museums worldwide and bring them together in the one place, creating a kind of ‘master museum’. All of this data will be...

Preparators are specialist staff working in museums and universities worldwide. They perform a very wide variety of tasks from fieldwork excavations, to specimen conservation. Any fossil has to be prepared for use, whether its to expose specific parts so that they can be studied, or to preserve and reconstruct a specimen so that it can be displayed in a museum gallery. Vertebrate preparation is an...

This year the annual meeting of the Geological Society of America was held in Baltimore, Maryland. This is one of the largest conferences that palaeontologists attend, with over 6000 attendees from all fields of Earth Sciences. Caitlin and Laura went along and talked to many of the palaeontology researchers who had come to present their work on posters and in talks.

Pterosaurs were the first vertebrates to achieve powered flight, and lived in the skies above the dinosaurs during the Mesozoic. They're often mistakenly identified as dinosaurs, but are in fact a separate, closely related group. This group has recently undergone a revival, with more research on pterosaurs happening now than ever before. Where are they found? How diverse was this group? How did th...

The last part of our coverage from the 75th annual meeting of the society of vertebrate paleonology. In this part Caitlin speaks to Professor Christopher Smith about the history of the society, how it was recorded and archived, and how this information is being collected and maintained into the future.

In the second part of our SVP coverage we have interviews with some of the researchers on the scientific content of their posters and conference presentations.

The Society of Vertebrate Paleontology annual meeting is the largest conference each year for the world's vertebrate palaeontologists to present their work, network with each other, and find out what everyone else is up to. The first part of our coverage from the 2015 meeting in Dallas Texas includes interviews with palaeontology educators and museum specialists.

The ‘Crystal Palace Dinosaurs’ are a series of sculptures of extinct animals including dinosaurs, other extinct reptiles and mammals, which can be found in the grounds of the Crystal Palace in London. Commissioned in 1852, these are the earliest examples of dinosaur sculptures in the world. In fact, the first dinosaurs had only recently been discovered some 30 years earlier. Why were these models...

Ankylosaurs are a group of non-avian dinosaurs best known for their armour, tank-like bodies, and sometimes large tail clubs. First appearing in the Jurassic, they were common in Late Cretaceous ecosystems, with several species known from around the world. But how different were these species really? And just where did they evolve from? What was that tail for? Dr. Victoria Arbour of the North Caro...

Melanin is a pigment that is found across the animal kingdom. Melanosomes, the organelles that contain melanin, have been found preserved in fossil feathers and melanosome shape has been used to infer the original colors of birds and dinosaurs. Today we’re talking to Caitlin Colleary whose paper - on her Masters research at the University of Bristol - delves into detail regarding the structural an...

The Symposium of Vertebrate Palaeontology and Comparative Anatomy (SVPCA) annual conference was held at the University of Southampton National Oceanography Centre at the beginning of September. This is the first year we've covered this event, and covered a wide range of topics in vertebrate palaeontology. We spoke to several people, which you can listen to here, including information on Romanian a...

Eurypterids, or ‘sea-scorpions’ are an extinct group of chelicerates: the group containing the terrestrial arachnids (such as spiders and scorpions) and the aquatic ‘merostomes’ (represented today solely by the horseshoe crabs). They bear a gross-morphological resemblance to scorpions (hence the informal name) but, in being aquatic, may have shared more in common with horseshoe crabs. They inhabit...

On today's episode we're revisiting Mistaken Point , Newfoundland, Canada. At this lagerstätte it is possible to find large bedding planes full of Precambrian organisms called rangeomorphs. These are an enigmatic group, which still can't be placed on the 'tree of life'. We are joined by Dr Emily Mitchell of the University of Cambridge, who's recent paper in Nature was able to show that you don't n...

Synapsids are one of the major groups of terrestrial vertebrates. They first appear in the Carboniferous period and since that time have gone through many radiation and extinction events. But what did these first stem-mammals look like, how did they live and how do they differ from modern mammals? These may sound like simple questions, but there is an underrepresentation of terrestial deposits fro...
