A Visit To the McWane Science Center, Part II: Southern Sea Monsters

In the previous post, we took a look at the Alabama Dinosaurs exhibit at the McWane Science Center in Birmingham, Alabama. However, as you may remember from the last post, much of Alabama was underwater during the Cretaceous Period, submerged by a shallow seaway.

Notice how much of Alabama is submerged by a shallow seaway.

The warm waters of this shallow sea teemed with life, and after more than 75 million years, the fossil record of these marine organisms can be found in Alabama, with a diversity and richness far surpassing the state's known collection of dinosaur fossils from this time. McWane presents a sampling of this prehistoric marine life in the sister exhibit to Alabama Dinosaurs, fetchingly entitled Sea Monsters...

A Visit To the McWane Science Center, Part I: Dinosaurs of the Deep South

Sorry for the long absence. Hopefully there will be new content -- including art -- here soon.

Anyway, if you should ever find yourself in Birmingham, Alabama, as my family and I did last week, a day at the McWane Science Center is sure to prove a day well spent. McWane features a museum as well as an IMAX, and most of the exhibits are geared toward kid-friendly interactivity: there is a hall of physical-science based challenges, brain teasers, and the like, an aquarium featuring a shark and ray touch pool, and space for visiting exhibits, which at the time of our trip was hosting an interesting, interactive-heavy exhibit on the history toys and games over 20th and 21st centuries. Of course, as soon as we'd paid our admission, I dragged the family up a flight of stairs to get to what we all* came to see: the dinosaurs.

Still Alive

No worries - if anyone was worried - Noah's Ravens is still alive. I hope I'll be able to have a large, art-heavy post/series of posts up in the next week or two.

Thanks for your patience.

Roll Up For the Roadshow

On Saturday, I participated in the kickoff of the Cambridge Science Festival in Cambridge, Massachusetts. Myself and one of the other student employees at the Beneski were asked to help run a booth showing fossils collected from western Massachusetts. The booth was organised by a group called the Jurassic Roadshow, who collect fossils and educate people about our geologic past, often at events such as this one; they kindly invited Beneski Museum docents to get involved with the event.

Day of the Diplodocids

Welcome, true believers, to a Very Special installment of Noah's Ravens. As you have no doubt seen while scrolling through Facebook or Twitter or while idly surfing the web, yesterday marked the appearance of a new (very long) paper reviewing the diplodocid sauropods, 'A specimen-level phylogenetic analysis and taxonomic revision of Diplodocidae (Dinosauria, Sauropoda)' by Emanuel Tschopp, Octávio Mateus, and Roger B J Benson, published open-access in PeerJ. Although I'm certain you've all had time to read it, pore lovingly over the cladograms, savour each and every word about each and every specimen, and completely lose yourself in the figures depicting small chunks of bone, I thought it might be nice to have a brief(ish) round-up post that covers some of the big ideas of the paper in a condensed(ish), hopefully-easy(ish) read.

It was nice knowing you, Diplodocus longus, but all good things
must come to an end. Read on to find out why. Legs belonging to

If there is one animal that could be considered the living (or, ah, once-living) emblem of the Ice Age, that animal is undoubtedly the woolly mammoth. But second place is nothing to sneeze at, and second place is firmly defended by a pair of 20-centimetre-long canine teeth. Yes, in the popular imagination, the second-most iconic animal of the Ice Age is the ferocious sabretooth tiger.

It's rather shame that there's not really such a creature as a sabretooth tiger.

Frederic Loomis Discovers Everything, Episode 1: Raiders of the Lost Continent

Around three million years ago, South America became connected to North America via the Isthmus of Panama, and an event called the Great American Biotic Interchange took place, where wildlife from South America moved north and vice versa. Prior to this, South America had been isolated from most of the rest of the world since the Cretaceous Period, and connected only to Antarctica until they separated about 30 million years ago, allowing little exchange of wildlife from other places in world. As such, South America was a 'lost continent,' a strange land cut off almost completely from the rest of the world, with its own array of unique organisms, the characters in their own isolated evolutionary story. It was into this strange world that the North American emigrants came some three million years ago, and it was into the fossil echoes of this world that a very different group of North Americans came in the early 20th century.
