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 as blood vessels and even proteins. Naturally, her research has been met with a whole wad of stiff resistance from the scientific community, seemingly for no other reason than “We don’t like the sound of that..”. Scientific rigour ftw!

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 energy flow within ecosystems. But was it the same million of years ago during the reign of the dinosaurs?

Imagine a natural world without decomposers. Carcasses would litter landscapes, and there’d be a neat smattering of faeces decorating everything like jam. Humans have adapted beyond this need for decomposers by creating the loo – dinosaurs weren’t so technologically efficient, and one can only imagine the issues T. rex would have trying to flush anyway.

Absolutely no sniggering – the dinosaur that looked like a cock

Dinosaur skeletons are a thing of pure beauty. Being able to see and touch something that has been dead for millions of years instills a sense of wonder; what did they look like, how did they behave, were they like anything we see today? Palaeontology is a science that raises more questions than it answers, but these questions are the ones that drive the science, but also maintain that sense of fascination that no other scientific field can lay claim to.

Every now and then, we are blessed with a true jewel.  Many can lay claims to the discovery of a dinosaur bone, even fewer to that of a whole skeleton. Celebrity status is achieved when one finds something that truly stands out, a dinosaur preserved in immortality with flesh, and these are the rarest of all.

Were dinosaurs the masters of social integration?

Back in the Late Cretaceous, the USA was divided. Not politically, but by a vast continental sea called the Western Interior Seaway, splitting the continent into two separate landmasses. The western one of these, known as Laramidia, played host to some of the popular dinosaurs like Parasaurolophus, or ‘Elvis’ in Pete Postlethwaite dialect, and the ceratopsian Chasmosaurus. One of the cool things about Laramidia though, is that you had a whopping great amount of these megaherbivorous dinosaurs, or omnomnomosaurs, living together in the same time and place. How could one area contain such a vast number and range of dinosaurs?

The underworld thief returns from the dead

So I don’t normally blog whenever a new dinosaur pops out the pages, but a new one, Acheroraptor temertyorum received quite a welcome back to the living world with this exquisite illustration by Danielle Dufault. I’ve asked for her permission to post on here, and it’ll appear on the front cover of Naturwissenschaften (December issue, probably), so defo worth checking out a hard copy!

Acheroraptor, in all its glory
