Today's most heavily blogged science story is probably the discovery of a new species of early whale. A team of researchers led by whale evolution expert Philip Gingerich discovered the remains - a largely complete adult male, and a female that was carrying a near-term fetus - during field work in Pakistan in 2000 and 2004. They've named the new species Maiacetus inuus.
If you're interested in learning more about this fascinating discovery and what it can tell us about the evolution of whales, here are a few links to check out:
The PLoS one paper that describes the species
Bora's collection of blog links
The article about the new find at Laelaps - if you don't read any others, read that one.

As always, it means nothing.
Since there are no such things as transitional animals, these these "Maiacitus" things are obviously just a another kind of bear. A huge, huge, ancient one with flippers and a tail that lived in the ocean.
Or maybe just another kind of whale. A really old one with with, um, feet.
Move along. nothing to see here.

Now I'm going to be poking around AiG and EN&V just to see if they say the entirely predictable thing. They won't pass this one up. Sigh, I should know better than to bother ... like I posted a little while back about hitting myself in the head with a hammer twice just to see if hurt the first time: "Did that hurt?" BASH! "I guess it did."

There is something that has always bothered me about Basilisaurus reconstructions. What is up with the tail? They ALWAYS show a long serpent tail with small flukes at the end. This makes no sense at all. To be efficient, the tail should be flattened, like a beaver's or sea snake's. Has anyone actually found impressions of the flukes, or were they just a WAG? A long flattened tail would seem to be a fine intermediate between a terrestrial tail and flukes.

I went over to LIVESCIENCE.com to see what they had to say and they were running a straightforward writeup of the story.
http://www.livescience.com/animals/090203-pregnant-whale-fossil.html
It had links to the U-Mi video.
Another PT-ite was telling me the other day that LIVESCIENCE.com was infested with teenage Darwin-bashers. I didn't see them then but they're out in force in the comments section of that article. And they are indeed the bargain-basement ... the average Darwin-basher that crashes PT would be embarrassed to use the arguments they do.

I thank Mike for a good post, these new fossils are fascinating. I thank stevaroni for a good chuckle.

Check Flickr -- nice shots of the reconstructed whale skeletons discussed in the articles.

Wow. Not only a new species, and not only a transitional species, but a near-term fetus? Surely that's considered winning the paleontology lottery.
I wish I could say more, but I'm still dealing with the coolness factor of the discovery.

Re: tail flukes on Basilosaurus...google reveals:
http://www.talkorigins.org/features/whales/
Although no tail fluke has ever been found (since tail flukes contain no bones and are unlikely to fossilize), Gingerich and others (1990) noted that Basilosaurus's vertebral column shares characteristics of whales that do have tail flukes. The tail and cervical vertebrae are shorter than those of the thoracic and lumbar regions, and Gingerich and others (1990) take these vertebral proportions as evidence that Basilosaurus probably also had a tail fluke.

Not to knock PLoS One, well I guess to actually, but how was this not published in Nature or Science?!

Mr. Gee, got a link to that Conservapedia trick?
Also, Firefox keeps telling me that "Conservapedia" isn't a word. I don't have the heart to add it to the dictionary and tell FF otherwise.
