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.

From impact factors to impact craters

April 9, 2013

Day 2 in the Big Brother house (aka the European Geosciences Union General Meeting). There’s no where near enough beer, and tensions are getting high. A horde of angry horses have invaded the lower levels, and taken the President of Austria hostage, with demands of lowering the Fair Straw Tax.

But throughout all the acid-fuelled hysteria, two events have stuck out so far today. The first was a workshop discussion on open access publishing for early career researchers (ECRs), hosted by a new Editor for the EGU’s publishing house, Copernicus. Unfortunately, this event confirmed a lot of the current issues with the development of open access policies globally, in that there has been a serious communications breakdown about the effects the policy transitions, particularly in the UK now that Research Councils UK’s (RCUK) open access policy has come into play (April 1st), will have on how and where ECRs can publish. Here are comments on several of the more prevalent points raised:

Curiosity continues to rock on Mars

April 8, 2013

NASA might be having a rain-check on its outreach activities, but that’s not why Curiosity has gone silent the last few days. Every once in a while an event known as the Mars Solar Conjunction places Mars’ orbit directly behind the sun with respect to Earth, and makes communications impossible. Transmissions have ceased until May 1st, when the red planet will pop back into digital sight. Until then, Curiosity is working on the ‘B-side’ (like the cool side of the pillow) of its systems and operating autonomously.

In the mean time, I’ve been fortunate enough to be at the MSL (Mars Science Laboratory) Press Conference here in Vienna, with the latest from the little (1 tonne) science-savvy robot. During the current down time, it’s a chance for the teams to begin to really process the data and get the science out there (see here for where Curiosity has got to so far). This is a snippet of what to expect in forthcoming publications.

Can fossil mammals help us with our conservation efforts?

Can fossil mammals help us with our conservation efforts?

How can the dead help the living? This is a question a lot of fossil-fanatics have bent a lot of time towards over recent years, partially due to a desire to make palaeontology ‘relevant’ as a modern science, and secondly to help guide our efforts in conservation biology. A new series, edited by my supervisor Dr. Phil Mannion and others, focusses on the way we interpret palaeobiodiversity, biodiversity in the fossil record, for different groups and the issues and solutions facing the field. The final article in the volume struck me in particular.

How can fossils help us to protect these now and in the future? Source.

Dwarf crocodiles in Munich

April 4, 2013

My PhD consists of two parts. The first is investigating the dynamics of biodiversity across the Jurassic/Cretaceous interval about 145 million years ago. I want to see if when we consider the biases of the fossil record whether there was a ‘hidden’ mass extinction, and what were the ecological, physiological or environmental factors that correspond to this. This involves looking at turtles, birds, dinosaurs, marine reptiles, lizards, snakes, crocodiles and any other tetrapod group at the time – that’s anything with four feet, flippers or wings (see previous post for an update on all this jazz).
