In 2007 Nicolas Cage and Leonardo DiCaprio got into a bidding war for a 67-million-year-old tyrannosaurus bataar skull. Cage won, but later found out the skull had been illegally smuggled into the United States. He will return it to the Mongolian government.
According to a 2013 story in the Telegraph, “the skull was obtained by IM Chait from Eric Prokopi, a self-described ‘commercial palaeontologist’ who pleaded guilty last year to illegally importing fossils from Mongolia and China.” Read the rest

It may be the longest coprolite ever found, a truly magnificent turd, virtually a relief casting of a horribly constipated dinosaur's ancient animal's colon.
Full Details for Lot 340
This truly spectacular specimen is possibly the longest example of coprolite - fossilized dinosaur feces - ever to be offered at auction. It boasts a wonderfully even, pale brown-yellow coloring and terrifically detailed texture to the heavily botryoidal surface across the whole of its immense length. The passer of this remarkable object is unknown, but it is nonetheless a highly evocative specimen of unprecedented size, presented in four sections, each with a heavy black marble custom base, an eye-watering 40 inches in length overall.

This table is not for pooping. It's for tea. But it is made of poop — specifically fossilized hunks of fish poop, encased in a crunchy shell of clay and rock. The fossilized poops — called coprolites, which is basically just fancy Latin for "fossilized poop" — are the spiny-looking bits in the center of each circular inlay on the table top. (Technically, the name translates as "dung stone".)
The table belonged, appropriately, to the Rev. William Buckland, the man who gave coprolites their fancy name and proved that they were, in fact, fossilized poops.
The table resides at England's Lyme Regis Museum. You can read more about Buckland's work and the details of the craftsmanship and restoration behind the table at their website. Earth Magazine also has a lovely article on coprolites, including important information that will help you distinguish between fossilized poop and stuff that just looks like fossilized poop.

David Cain of Middletown, Ohio is selling off his late father's massive collection of fossils that takes up several rooms in an unmarked storefront. Cain says the most valuable items are 200 megalodon teeth, and a dozen dinosaur egg nests. He'd like to get around $250,000 for the whole lot. The challenge, says Dale Gnidovec, collection manager at Ohio State University's Orton Geological Museum who checked out a video of the collection, is that what he saw is "readily available at any large fossil shop and many of them have been ‘enhanced’ by the craftsman. It is also very depressing to see so many fossils that have been stripped of their scientific value by not having exact locality and geologic information.” Interestingly, Cain is selling the fossils so he can grow his own collection of historical juggling props. It's apparently the third-largest in the world. Cain is a professional juggler whose act is called "Juggler for Jesus."

The coelacanth is one of a small handful of living fishes that are probably closely related much more ancient, extinct creatures — including, the first fish to haul itself up onto land. Now scientists have sequenced its genes and are digging through the data in search of genetic clues to how fish and land-dwelling animals are connected to one another
. Among the finds so far, a gene that seems to be connected to how animals grow placentas. Coelacanths don't have placentas, but they do have eggs that hatch inside their own bodies. Read the rest
Superstorm Sandy brought fossils up from the ocean depths.
Yesterday, I posted about Pegomastax africanus, a parrot-like dinosaur whose fossil was discovered not in a remote waste in some far corner of the world, but in a rock that had sat in storage at Harvard University for 50 years.
In the post, I tried to explain why something like that could happen. The simple fact of the matter: A successful archaeological or paleontological dig will produce far more material than the original scientists have time (or money) to sort through, process, and examine. So lots of stuff ends up sitting in storage.
That led BoingBoing reader Matt Fedorko to some interesting speculation:
"...This seems like a perfect opportunity to exploit 3D scanning technology to put the shapes of fossils, at least, into some kind of digital storage area where other researchers could look at a dig's haul and start to work with them spatially, or beside any of the other data that is collected in the field or logged during the cataloging procedure."
Now, Charles Q. Choi, a journalist who wrote about the discovery of Pegomastax africanus, says that Matt's idea isn't all that far-fetched. In fact, scientists already do something like this with the fossils that do get closely examined. Read the rest
A friend pointed me today toward the awesome work of Surly Amy (aka Amy Davis Roth), who makes really neat ceramic jewelry with science/skeptic themes. Some of her pieces are really simple and not super artsy—a pendant that says "This is what an atheist looks like", for instance. That's fine, but it's not the stuff I'm super excited about.
Instead, I really dig Roth's work that focuses on archaeology and paleontology—like a necklace printed with the silhouette of an archaeopteryx fossil on a crackled background that makes me think of broken stone; earrings decorated with ammonites; and a kick-ass bracelet that manages to make trilobites look just a little punk rock.
I also enjoyed reading Roth's bio on her Etsy page. It's long, but the two key takeaways are great:
1. I'm not as surly as I used to be.
2. Life is hard and it often sucks but sometimes, if you keep trying, things will get better!

Retinal neuroscientist and photographer Bryan Jones sends in this gorgeous shot of an archaeopteryx fossil displayed in the Museum für Naturkunde in Berlin, Germany.
"As a biologist, seeing this fossil represents something of a pilgrimage," says Bryan, "[Visiting this museum is] a journey that all biologists would benefit from making."

This particular sample was found in the Solnhofen limestone formation in Bavaria and is the basis for the link between the dinosaurs and the feathered birds. Archaeopteryx itself is a feathered theropod, but is though of as the oldest documented bird dating back approximately 150 million years ago.
The fossil was found in 1874 by Jakob Niemeyer who traded it to Johann Dorr for a cow. Johann then sold the fossil to Ernst Haberlein for 2,000 German Marks. This sale was then turned around to the founder of Siemens, Werner von Siemens for 20,000 German Marks for the University of Berlin which has provided this specimen to scientists around the world as the best preserved specimen found with elegant feathers and an exquisitely preserved skull.
Teenagers, beware! Here is another very good reason to never, ever have sex. Like these 50-million-year-old turtles, you could get so caught up in the act, that you don't notice you are sinking into a bog full of toxic volcanic gasses. It's a real risk! This happened to more than one pair of filthy, sex-having turtles. And condoms will not save you.
The researchers analyzed nine pairs of the turtles. Each pair was apparently made up of a male and a female — the females are slightly larger than males, have shorter tails and apparently had a hinged lower shell that may have helped them lay large eggs.
In addition, the turtles in each pair always had their rear ends oriented toward one another. Finally, in two of the pairs, "the tails of the partners are aligned with each other," Joyce said. "This is the very position in which the tails are held when living turtles mate. This observation is the true smoking gun.
"No other vertebrates have ever been found like these, so these are truly exceptional fossils," Joyce said.

The Leakey family is like the Kennedys, but for paleoanthropology instead of politics. Think about any hominin fossil or artifact you can name. Chances are, there was a Leakey involved in its discovery. Louis Leakey was one of the first scientists to champion the idea that humans had their origins in Africa. For three generations now, his family has carried out active paleo excavations in eastern Africa, especially the countries of Tanzania and Kenya.
The first generation—Louis Leakey and his wife Mary—were most associated with Tanzania's Oldupai Gorge. But their son Richard, his wife Meave, and their daughter Louise have all spent their careers focused on Lake Turkana, on the border between Kenya and Ethiopia. The site is the world's largest, permanent desert lake. Undisturbed by modern development, in a spot where millions of years of flowing water have washed deposits and fossils down from the rift valley—Lake Turkana is an excellent place to search for human ancestors and our ancient relatives.
On Wednesday, PBS will air an hour-long documentary on the Leakeys' work at Lake Turkana. Part biography of Richard Leakey and part exploration of human history—Bones of Turkana will air May 16th at 9:00 pm central and again on May 21st at the same time. Yesterday, I got the opportunity to speak with Richard and Meave Leakey. We talked about human evolution, the scientific promise of Lake Turkana, the process of paleo fieldwork, and the lasting impression of the Leakey legacy. Read the rest
Re-creation of Jurassic Cricket song, from Bristol University in the UK by qparker
Listen to this recording. It sounds a little like Sputnik, but it's actually a noise that's not been heard in 165 million years.
This is the song of an extinct species of bush cricket, the fossils of which have been found in China's Inner Mongolia region. Researchers recreated the sound by studying the fossil remains of the crickets' sound-producing organs. From the BBC:
A "plectrum" on one wing was dragged along a microscopic comb-like structure on the other. This produces a continuous "chirp" as the male insects rub, or "stridulate" their wings in a scissor-like motion. Dr Zapata described this stridulation as similar to playing a tiny violin.
Dr Zapata then set out to calculate the frequency of the tone, which denotes how high- or low-pitched it sounded. To to this, he simply compared the size and shape of its music-making or "stridulatory" instruments to those of living cricket species
There are modern bush crickets, but their songs are played at a higher pitch. The low tones produced by this extinct cricket imply that it might have been best adapted to do its singing on the ground, rather than elevated on branches or tall stalks of grass. Lower pitched sounds travel further from that elevation than a high-pitched one would.
