This was originally posted here. Mass extinctions are insanely catastrophic, but important, events that punctuate the history of life on Earth. The Jurassic/Cretaceous boundary, around 145 million years ago, was originally thought of to represent a mass extinction, but has subsequently been ‘down-graded’ to a minor extinction event based on new discoveries. However, compared to other i ...[Read More]
Welcome to guest blogger Dr. Sabine Lengger!
Hi readers of “Green tea and Velociraptors”, my name is Sabine Lengger, I am a scientist, and I am an avid reader of Jon’s blog too. I started out my scientific career as a chemist / biochemist, and became more and more fascinated by the fields of environmental chemistry and molecular palaeontology. Since Jon spends all day [apparently] writing his thesis these days and asked for a guest writer, I ...[Read More]
How fast was the demise of the dinosaurs?
It’s dark. It’s always dark these days. Lights in the sky burn your eyes, so you keep your face to ground in the hopes that they’ll go away. But they don’t. The air is heavy. Heavy with poisons that make it difficult to breathe. Heavy with foreboding dread. You, my unfortunate friend, are going through a mass extinction! There have been five periods of mass extinction in the past. These represent ...[Read More]
Middle-Earth gets a geological makeover
As if J. R. R. Tolkien wasn’t brilliant enough with his creation of Middle-Earth, it appears that using his numerous maps and illustrations provided, supplemented by observations from within the texts themselves, a geological reconstruction can be achieved! I recently came across this old article from the Proceedings of the J. R. R. Tolkien Centenary Conference, Oxford, England, 1992, and figured ...[Read More]
Macroecology – scaling the time barrier
If there was ever an overdue discussion in palaeontology, it was how we reconcile the differences in time scales when looking at different periods in our history. This is becoming increasingly more important as scientific research is being asked to have demonstrably greater ‘impact’ in terms of some social, economic, or environmental relevance, and for palaeobiologists and palaeoecologists, this m ...[Read More]
Double-whammy signifies the demise of the dinosaurs
The meteoric impact that wiped out the non-bird-line dinosaurs is an iconic image of life and death on Earth. It signifies a point in time when life changed forever. It took from us animals that we will never see again. But was it just a single strike that created these winds of permanent change? The crater from Chicxulub in Mexico is the scapegoat for taking dinosaurs from us, but did it have a p ...[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 published a cool paper late last year on the ...[Read More]
What do we know about the origin of flowering plants?
This is a guest post by Dan Peppe. He is an Assistant Professor in the Geology Department at Baylor University. His research interests are focused on reconstructing ancient climates and ecosystems in North America and East Africa and on developing new and improved palaeoclimate and palaeoecological proxies using methods in paleobotany, sedimentary geology, and paleomagnetism. More information a ...[Read More]
Geology beyond science
This was originally posted at: http://www.nature.com/scitable/blog/earthbound/geology_beyond_science So people who read this blog (*one person cheers off in the distance*) may have noticed that my partner-in-crime, Jane Robb, recently abandoned me to the fusty claws of Nature. *sniff* Fear not though! Jane is pursuing awesome things now with the European Geosciences Union, the other organisation I ...[Read More]
Geologists as a social stigma?
So I was browsing for content for future blog posts the other day, and came across this video from Friends (the show people of my era grew up with). Ross is a palaeontologist, so naturally one of the coolest, smartest and sexiest of all the science breeds, but takes a little dig at geologists here in a social context. Now compare that to this video from American Dad, in which geologists are portra ...[Read More]
