Many years ago, a sudden event occurred that changed everything. Or at least, that is what we think now. But in truth, the event took longer than many today believe, and many of the specific details, the exact order of events, the actual meaning of each detail, are not fully understood. Indeed, in the process…

Keller has been one of the leading voices opposing the impact KT boundary extinction hypothesis. According to a press release from her university, she has more on this matter.

… has been found. Inside the fish’s skull, in fact. This is from a chimaeroid fish, which today are fairly rare but during the Carboniferoius were quite common and diverse. There are really two aspects of this find that are especially interesting. One is the 3D imagery that was obtained of the ancient fossilized brain,…

A most amazing set of spoor

Dino spoor, that is. A recently reported finding in PLoS ONE clarifies a number of questions about how certain dinosaurs held their front limbs (zombie/Frankenstein-position palm-down vs. huggie-wuggie palms-facing-each-other). This research confirms … that early theropods, like later birds, held their palms facing medially, in contrast to … prints previously attributed to theropods that have…

OMG, Ken Ham is Right!!11!!

PLoS Paleontology Collections

PLoS ONE is a veritable fire hose of OpenAccess research. Which is nice, but how do you browse a fire hose? By using the PLoS ONE collections you can track your favorite topic or delve into the earlier literature or just browse around. And now, starting just moments ago, there is a PLoS collection on…

How diverse were early hominoids?

And hominids. We know the fossil record underestimates diversity at least a little, and we know that forested environments in Africa tend to be underrepresented. Given this, the diversity of Miocene apes may have been rather impressive, because there is a fairly high diversity in what we can assume is a biased record. But I’d…

Did Triceratops fight with their faces?

Or, more accurately, did these dinosaurs either engage in intraspecific combat (such as territorial or mating contests among males) or fight predators such as Tyrannosaurs, like in the movies? Well, one thing we know for sure: If any folklore, belief, or ‘fact’ related to a fossil species sits around long enough, eventually someone will come…

An article released moments ago in PLoS ONE, by Gingerich et al., describes one of the more interesting fossil discoveries ever. To cut right to the conclusion: We now have reason to believe that the proto-whale Maiacetus inuus, a true transitional form, gave birth on land, not in the water. Artist’s conception of male Maiacetus…

One of the most interesting and exciting stories in science is that of the Younger Dryas. The Younger Dryas was a climate event that had important effects on human history, and that has been reasonably linked to some of our most important cultural changes, and ultimately some evolutionary changes as well. That is one reason…
