Paleontology

The iconic Coelacanth are fish well-known as ‘living fossils’. Coelacanths were thought to have died out with the dinosaurs and then a living one was caught off the coast of South Africa in 1938, sending waves of excitement throughout the scientific world. 

Is it a shrub?  No one really knows. A fossilized specimen, a roughly elliptical shape with multiple lobes, totaling almost seven feet in length, was unveiled today at the North-Central Section 46th Annual Meeting of the Geological Society of America, in Dayton, Ohio.

Around 450 million years ago, shallow seas covered the Cincinnati region and harbored one very large and now very mysterious organism. Despite its size, no one has ever found a fossil of this "monster" until its discovery by an citizen paleontologist, Ron Fine of Dayton, last year. 

Palaeontologists have found that not all Easter eggs come from the same “parent” species -  some could be from dinosaurs, including a new species from the Pyrenees. An international group of researchers has helped to determine that dinosaurs have shaped the Easter eggs we buy.

Scientists were investigating whether 70 million-year-old fossil eggs found in the Pyrenees were laid by birds, or their dinosaur ancestors - researchers from the University of Leicester extended the study further by comparing Easter egg shapes to those of birds’ and dino eggs.
A previously unknown species of giant, feathered tyrannosaur has been discovered in China, making it the largest-known feathered animal, living or extinct.

Tyrannosaurus rex and its cousins lived until around 65 million years ago and earlier relatives are thought to have been much smaller than the T-Rex we have come to know, but this notion has been challenged by the discovery of three specimens of a new species of tyrannosauroid from the Lower Cretaceous, 125 million years ago. The dinosaur, Yutyrannus huali, whose name translates from Latin and Mandarin as ‘beautiful feathered tyrant’, shares some features with derived tyrannosaurs, but has three-fingered forelimbs and a typical theropod foot, like other early tyrannosaur relatives.

This is Beiyanerpeton jianpingensis, prepublished this week in PNAS.

I couldn't possibly call myself a paleontology blogger and not post the fossil below as an article. Happily, I notice that it is friday today and so this can come under the banner of my oft forgotten feature of friday fossil.


It's always the way.

Within the last week, there's been so many fantastic papers out that I literally have no idea where to start. People always seem to publish these things when I am most busy. It is most inconsiderate.

Anyway, together with a few other things I never got round to posting, I thought I might stick a little compendium up of some recent cool papers. I'm not planning on making this a regular feature - especially when you see how committed I am to my other "regular" feature (sorry about that, Helen!). So for this last week, here are my picks from the last week or so of paleontology for you to browse at your leisure.

I am pleased to present once again an interesting TED talk. O.K., the talk is a little on the slow side, but Jack Horner’s Shape Shifting Dinosaurs is worth watching, for it shows yet again something that cannot be repeated often enough: Scientists have a big huge ego and are therefore some of the easiest fooled people around.


Every 6 months or so these days it feels like we find the earliest animal life. More often than not, said life is something ugly that turns up in a bucket after dissolving rocks in acid.

Well, it's been a while, but here is the latest candidate:



...this turns up.



This thing is Siphusauctum gregarium, and is known from over 1000 specimens. It probably looked something like this,
