AMNH Separates Iconic Battling Dinosaurs in Rotunda

The American Museum of Natural History began the process of separating two long-time combatants -- barosaurus and allosaurus skeletons -- that have shared the same display mount in the Theodore Roosevelt Rotunda since they were first installed in 1991. The separation kicked off with curator Mark Norell overseeing the first ceremonial cut in the mount.

Here Be Dragons: How the Study of Animal and Plant Distributions Revolutionized Our Views of Life and Earth

I'm happy: another book review of mine was just published, this time, by Science magazine. This book, Here Be Dragons: How the Study of Animal and Plant Distributions Revolutionized Our Views of Life and Earth (Oxford University Press: Oxford; 2009), is by Dennis McCarthy, a researcher at the Buffalo Museum of Science in Buffalo, New York. In short, I liked the book and I thought it was generally well-written, but it could easily have been twice as long and provided more depth and nuance to the points the author was discussing. You can access the review on the Science site or you can ask me for a copy and I'll happily email it to you [PDF].

Australia's oldest painting?

An Australian Aboriginal rock art may depict a giant bird that is thought to have become extinct some 40,000 years ago, thereby making it the oldest rock painting on the island continent. The red ochre drawing was first discovered two years ago, but archaeologists were only able to confirm the finding two weeks ago, when they first visited the remote site on the Arnhem Land plateau in north Australia.

UV, You See? Black Light Reveals Secrets in Fossils

Figure 1. The holotype of Microraptor gui, IVPP V 13352 under normal light. This shows the preserved feathers (white arrow) and the 'halo' around the specimen where they appear to be absent (black arrows). Scale bar at 5 cm. [larger view]
DOI: 10.1371/journal.pone.0009223

It has long been known that when exposed to ultraviolent light, fossilized bones and shells -- and even tissues -- will fluoresce, thus rendering undetectable details visible. But this technique has been used mostly to visualize fossilized invertebrates, and inexplicably, has rarely been used to investigate hidden structures in most vertebrate fossils. But a team of paleontologists recently studied the Microraptor gui holotype using UV light.
