It’s time for Mammals March Madness, the tournament in which animals battle for supremacy based on their physiology and behavior, with a little bit of luck thrown in just as you would want in any competition. Note: This is a … Continue reading
Editor’s Note: Today’s post comes to you from Jeffrey Moussaieff Masson, bestselling author of nine books on the emotional lives of animals. It is pretty common to hear the expression “crocodile tears” in reference to somebody who does not feel … Continue reading
My next blog post series will be just like its predecessor, except these fights will be between animals in the Cenozoic Era. And, to keep it on topic (dinosaurs) the fights will involve birds, which are a type of dinosaur. I might also include crocodilians in my posts, to satisfy one of our guests (I’ve

Out in the field you encounter all sorts of wildlife and while mosquitos are the most frequent (and most unwelcome), they generally don’t interfere with your equipment or your data. The same can’t be said for all animals though, and many scientists have to strap their equipment out of reach, barricade it with barbed fences
Those of its inhabitants who had succeeded in surviving would find themselves at last face to face with the relentlessness of a scarcity of water constantly growing greater, till at last they would all die of thirst, either directly or indirectly; for either they themselves would not have water enough to drink, or the plants or animals which constituted their diet would perish for lack of
Form, function, and evolution of living organisms. 2014. J. R. Banavar, et al. PNAS
New research suggests that the shapes of both plants and animals evolved in response to the same mathematical and physical principles.
Kleiber’s Law (metabolism = mass3/4), one of the few widely held tenets in biology, shows that as living things get larger, their metabolisms and their life
A National Geographic article explores the diversity and incredible preservation of China’s Jehol fossils. The animals are thought to have been killed, transported, buried and preserved by ash produced by pyroclastic flows. Some researchers described it as a “Pompeii for
Skulls are fascinating. How the develop is fascinating, but what we end up with just as much. What these hard bits in the heads of animals can tell us about the not-hard bits of the head is extensive, but we’ve … Continue reading
From Today In Science History:
In 1868, Charles Darwin's book - Variation of Animals and Plants under Domestication - was published. He was 58. It is probably the second in importance of all his works.
This was a follow-up work, written in response to criticisms that his
theory of evolution was unsubstantiated. Darwin here supports his views
via analysis of various aspects of plant and
I assume this is supposed to be the southwest U.S. during the Late Triassic, but there is a hodge-podge of animals from different ages. Still pretty cool though; however, I wish the aetosaur and photosaur were on the scene a little longer, and where is the ubiquitous Postosuchus?
Some animals have overbites. it’s fairly common enough that animals (and humans) are born where the upper and lower dentition do not precisely match. Sometimes this alignment can be severe and affects diet. Other times, it is hardly noticeable. But … Continue reading
Dinosaurs are a varied group of animals of the clade Dinosauria. They first emerged during the Triassic period, 231.4 million years ago, and were the main terrestrial vertebrates for 135 million years, from the commencement of the Jurassic (about 201 million years ago) till the end of the Cretaceous (66 million years ago), when the Cretaceous–Paleogene annihilation event led to the annihilation of most dinosaur groups at the close of the Mesozoic Era. The fossil record points that birds [...]
I spent an hour or so putting some bryozoan fragments back together and got two nice branching colonies of Atactotoechus furcatus.A plate of matrix with both shown in position.The piece on the lower right detaches from it's spot and can be viewed in three dimensions. For purposes of conversation, this is the anterior side.And this is the posterior side.A close up of one of the branches shows some of the individual zooids where the animals lived.This is the other branch which is affixed to the [...]
I never thought I'd miss Kenneth Branagh quite as much as I do now. Nevertheless, having solemnly journeyed to my local Shiny Multiplex Enormodome to see the Walking With Dinosaurs movie, it's the slightly over-earnest tones of thespian Kenny that I long for. For you see - and forgive me if you've heard this already - WWD 3D features dinosaurs that talk. And talk. And talk.Talk v teeth. Image from here.Apparently the victim of test screenings attended by morons and/or jittery studio heads, WWD [...]
Feathery dinosaurs can be an acquired taste. Not everyone likes seeing animals that have traditionally been wrapped in

Because Wayne Barlowe's an awfully talented sort of person, may I present a handful more of his dinosaur paintings, as featured in An Alphabet of Dinosaurs. On no account should you miss part 1 if you haven't seen it yet. Forward, Barlowe!One of the more striking aspects of Barlowe's work, coming as it does from the 1990s, is how much it presages certain trends in today's more, shall we say, avant-garde palaeoart. Of course, he also takes many cues from Kish and Henderson - I'd wager on the [...]

What are Brachiopods?
Brachiopods are actually a PHYLUM of animals. That's right a whole GROUP of animals that most folks have probably never heard of!

Brachiopods are a very old, group of invertebrates that live ONLY in the ocean. They have two shells (and are superficially similar to mussels) but are better known in several other

We've established by now that John McLoughlin's Archosauria was a beautifully bold, often highly prescient book, dedicated to overturning notions of dinosaurs as 'great fossil lizards' that were nature's way of killing time before those 'superior' mammals took over the place. McLoughlin illustrated feathered theropods and supercharged sauropods at a time when the number of people doing so could be counted on one hand. Given its boldness, it's surprising that Archosauria so infrequently [...]
Animal populations can have a far more significant impact on carbon storage and exchange in regional ecosystems than is typically recognized by global carbon models, according to a new paper authored by researchers at the Yale School of Forestry & Environmental Studies (F&ES).
In fact, in some regions the magnitude of carbon uptake or release due to the effects of specific animal species
While nothing could match the feathered theropods in terms of sheer prescience, there were illustrations of other animals in Archosauria that were groundbreaking in their own, perhaps more subtle ways (and now you know I'm not referring to the ceratopsians). McLoughlin may have been skimpy on the sauropodomorphs, but what he did provide was a tantalising glimpse into an exciting new era of palaeoart.(Yes, I'm finally doing jump breaks.) While his assertion that Plateosaurus was an habitual [...]
