Jon Tennant

Jon began university life as a geologist, followed by a treacherous leap into the life sciences. He spent several years at Imperial College London, investigating the extinction and biodiversity patterns of Mesozoic tetrapods – anything with four legs or flippers – to discover whether or not there is evidence for a ‘hidden’ mass extinction 145 million years ago. Alongside this, Jon researched the origins and evolution of ‘dwarf’ crocodiles called atoposaurids. Prior to this, there was a brief interlude were Jon was immersed in the world of science policy and communication, which greatly shaped his views on the broader role that science can play, and in particular, the current ‘open’ debate. Jon tragically passed away in 2020.

New dinosaur competes to be Europe’s largest ever land predator

This was originally posted at: https://theconversation.com/new-dinosaur-competes-to-be-europes-largest-land-predator-23997 Say hello to Torvosaurus gurneyi, the newly discovered theropod dinosaur that lived in Europe around 157-145 million years ago. It is potentially the largest land predator discovered in Europe and one of the largest carnivorous dinosaurs from the late Jurassic period. The identification of this new species plays an important role in developing …[Read More]

Erlikosaurus, the little dinosaur experiment

The evolutionary line from theropod dinosaurs is absolute. There is no question that this is one of the greatest stories that life on Earth has ever told us, But evolution is not linear; it’s chaotic. It’s bizarre. Along this theropod line, dinosaurs were experimenting – they were the evolutionary scientists of their time. One of …[Read More]

How do the chemical ghosts of dinosaurs help their preservation?

For some years now, Mary Schweitzer and her team have been researching the idea that organic molecules can be preserved for millions of years, specifically within dinosaurs. They have used a plethora of chemical and biotechnological techniques to demonstrate that, within animals like Tyrannosaurus rex, it is possible to find the residue of structures such …[Read More]

Where did all the mammoths go?

Let’s go meta. Recently, ecologist extraordinaire Dr. Jacquelyn Gill (or is it Professor cos of that weird American system?) wrote a wonderful review article on the extinctions that affected many large mammal species during the last 50-10,000 years. This period is known as the Quaternary, and was a time when ice ages were running rife …[Read More]

What are the key questions in palaeoecological research?

Last year, a throng of palaeoecologists from the world around descended into Oxford to discuss what the 50 most pressing questions in palaeoecology are. I was happy to see some great scientists and communicators among them, including Anson Mackay, Jacquelyn Gill, and Gavin Simpson, which gives me real hope that these questions were crafted with …[Read More]

Diving too deep?

A new initiative has just been announced that could help to revolutionise palaeontology. PaleoDeepDive is essentially an automated version of the Paleobiology Database, which is an online, professionally crowd-sourced and curated database of fossil occurrences pulled from the literature. They have a launch video here: I have a couple of reservations about this. Firstly, how …[Read More]

That’s no cloud..

Science is a deadly serious subject. Well, actually, no it’s not. In the slightest. Scientists are actually pretty fun people, despite their common depictions, and sometimes they have been known to publish smile-inducing articles. Take one Radagast the Brown of Bristol University (UK). This may or may not be a pseudonym, but either way he’s …[Read More]

Your poop or mine?

Back in the Mesozoic, lavatories probably didn’t exist. In fact, dinosaurs and other animals were probably pretty poorly mannered and just pooped wherever they felt like. But what or who cleaned up after them? In modern biomes, poop is decomposed by insects and bacteria of all breeds, and actually forms quite an important part of …[Read More]
