Interesting Science News

There are three interesting science news items the popped up today.

From National Geographic New Stegosaur With Odd Long Neck Discovered:

The neck of the new species, dubbed Miragaia longicollum, is considerably longer than the few inches seen on the average stegosaur neck. Miragaia’s neck is also very long compared to the dinosaur’s 19.6-foot (6-meter) body length.
The newly discovered stegosaur has 17 cervical vertebra, or neck bones–five more than a normal stegosaur and ten more than the modern giraffe.

The research is being published in The Proceedings of the Royal Society B and can be found here (pdf version).
From PhysOrg.Com Fossilised pregnant fish was one of the first animals to have sex:

However, recent findings such as embryos found in other placoderms, caused Johanson and her colleagues to take another look at the fossil.
‘The position of the embryo in this fish is the same as that of another found with a placoderm embryo in it in 2008.’ So they decided to reassess the description for the Incisoscutum ritchiei fossil.
The team came to the conclusion that the ‘meal’ was in fact a young fish developing in the womb of an adult.
‘The embryo in Incisoscutum ritchiei was in its final stages of development, inside its mother, waiting to be born,’ continues Dr Johanson.
‘This specimen shows just how important the Museum collections are because knowledge evolves and we have new interpretations that we can apply to fossils in the collections.’

Also from 13,000-Year-Old Stone Tool Cache in Colorado Shows Evidence of Camel, Horse Butchering – this one even has a movie:

The study is the first to identify protein residue from extinct camels on North American stone tools and only the second to identify horse protein residue on a Clovis-age tool, said CU-Boulder Anthropology Professor Douglas Bamforth, who led the study. The cache is one of only a handful of Clovis-age artifact caches that have been unearthed in North America, said Bamforth, who studies Paleoindian culture and tools.


Named the Mahaffy Cache after Boulder resident and landowner Patrick Mahaffy, the collection is one of only two Clovis caches — the other is from Washington state — that have been analyzed for protein residue from ice-age mammals, said Bamforth. In addition to the camel and horse residue on the artifacts, a third item from the Mahaffy Cache is the first Clovis tool ever to test positive for sheep, and a fourth tested positive for bear.

This one is really interesting and you should definitely read it.
