One of the biggest stories in paleontology this past month was the announcement of a beautifully complete fossil of an Eocene primate scientifically christened Darwinius messilae, and given the popular moniker “Ida.” A massive publicity campaign, including a book release and a documentary hosted by Sir Richard Attenborough, was launched in tandem with the fossil’s description in the online journal PLoS ONE. A backlash erupted throughout the science-minded blogosphere/twitterverse, deriding the more breathless claims that this one specimen was the “missing link” that will “change everything.”

Some of the earliest and most insightful comments came from Brian Switek at Laelaps. Earlier today, Brian compiled a collection of his and others’ Darwinius-related posts into a blog carnival called Uncovering “Ida”—an excellent resource for anyone interested in the interaction between science, publicity, and media (new and old).

• A team of paleontologists led by Philip Gingerich have described a new species of early whale. Buried along the shrinking shores of the Tethys Sea (and collected well above sea level in present-day Pakistan), the holotype of Maiacetus is the partial skeleton of a pregnant mother, preserved with the remains of its near-term fetus still in its womb. A more complete skeleton found one kilometer away is thought to be male, due to differences in size and pelvic proportion, and shows that this early whale retained the ancestral ability to stroll the shores on four fully-functional limbs (including an artiodactyl-style “double-pulley” ankle). The position of the fetus in the female indicates that Maiacetus gave birth head-first and most certainly on land, unlike modern whales that give birth tail-first into the water, which reduces the risk of drowning and helps orient the newborns parallel to their mothers. There are several excellent articles around the blogosphere for those who want to learn more, and the description is freely accessible through PLoS ONE at the link below.
  Fossils of female Maiacetus inuus with near-term fetus in utero, as found in the field. The female’s skull is shaded white (teeth brown), and other parts of her skeleton are shaded red. The single fetus, in birth position inside the mother whale, is shaded blue (teeth orange). The specimen was collected in three plaster jackets (blue dashed lines), and additional bones were picked up separately. The red dashed line indicates the edge exposed by erosion.

Apparently this is the first video footage of a live Hispaniolan Solenodon (Solenodon paradoxus), a secretive Caribbean mammal known primarily for being:

• Endangered
• Venomous
• Along with the Cuban Solenodon (S. cubanus), the last remnant of a distinct lineage of mammals going back 76 million years

More information about this footage (and higher quality video) can be found at this press release from the Durrell Wildlife Conservation Trust, or the related BBC story.

Although the project is still in its early stages (only about 45 specimens are listed as of this posting), it is already showing signs of becoming an amazingly useful resource. It is great to see someone using the open-source Simile widgets to organize natural history specimens—the Timeline component definitely has a lot of potential for paleonotological content. I’m particularly excited about the following planned feature:

• Embeddable snippets of fossils to be used in blogs, websites, etc.

I’m eager to see how this will be implemented—not only would it be handy to have a collection of ‘stock’ images and info for hominin specimens at one’s disposal, it might also be a great guide for researchers and institutions interested in creating embeddable content for specimens and objects in all kinds of collections.

Tip of the Hairy Museum toupee to Afarensis for bringing this to my attention.

From this story in the San Diego Union-Tribune, I learned of the life-sized (or larger) sculptures of Ricardo Breceda, who is in the process of installing an entire zoo of sheet metal megafauna on the Galleta Meadows Estate in Borrego Springs, California. The project appears to be a collaboration between sculptor Breceda, who was inspired to start sculpting prehistoric animals after watching Jurassic Park, and landowner Dennis Avery, who came up with the idea of “of adding ‘free standing art’ to his property” to recreate the area’s prehistoric inhabitants.

It’s hard not to be impressed with ambitious scope of this project, and Breceda’s sculptures seem to be a perfect fit for the arid landscape around Borrego Springs. I’m particularly fond of the character and detailing seen in the Gomphotherium (shown above) and the smaller ground sloths, like this little fella.

The NM Friends of Paleontology are meeting Monday, Nov. 17 at 7:00pm at the New Mexico Museum of Natural History and Science. This month’s meeting includes a talk by Larry Rinehart on some of the recent work he’s done on the allometry, growth, dimorphism and population structure of Coelophysis bauri from Ghost Ranch. The NMFOP meetings are free and open to the public.

On Thursday the 20th, geologist David Love and paleontologist Gary Morgan will be giving a talk on a 10 million year old oreodont recently unearthed at the Bosque del Apache Wildlife Refuge. The talk will begin at 3:30pm in the Macey Center auditorium at New Mexico Tech in Socorro (admission $5). More info about this find is online here.
