Jeffrey A. Wilson

Jeffrey A. Wilson also known as "JAW" is a professor of geological sciences and assistant curator at the Museum of Paleontology at the University of Michigan.

His doctoral dissertation was on sauropod evolution and phylogeny, and he has continued this work in cladistic analysis and revision of the group (see e.g. Wilson and Sereno 1994, 1998, Wilson 2005b, and especially Wilson 2002). With Paul Sereno, he defined the clades Macronaria and Somphospondyli (Wilson & Sereno 1998).

Wilson was also involved in the discovery and description of Pabwehshi pakistanensis, the first discovery of decent (diagnostic) Cretaceous crocodylian fossil remains from the Indian subcontinent, in the discovery of Rajasaurus narmadensis, the most completely known theropod dinosaur from India and a member of the family Abelisauridae, description of a number of North African dinosaurs (theropods and sauropods) from Niger, and rediscriptions of the Cretaceous sauropods Titanosaurus colberti (as Isisaurus) and Nemegtosaurus (previously thought to be a diplodocoid, but now recognised as a titanosaur).

His younger brother, Dr. Gregory P. Wilson, studies Mesozoic mammals and is currently an assistant professor in the Department of Biology at the University of Washington, and adjunct curator of vertebrate paleontology at the Burke Museum of Natural History and Culture.

The species T. colberti is renamed Isisaurus colberti)

gollark: That's basically what I said (the extra volume of halloween stuff mucks up the ratios).
gollark: Any opinions on my theory of what's going on with the pricing? Basically, I said that if extra dragons are introduced to the total but not the rest of the system (golds, whatever else), then rarer stuff's ratios will be affected more than common stuff, so the gold pricing goes crazy and nebulae stay the same.
gollark: 3.
gollark: My theory of what's up, copied from the forum thread:If many new eggs are being introduced to the system, then that will most affect the stuff which is rarest, by making it rarer by comparison, but commons will stay the same. As for why it happened now? Weekly updates, possibly.Example:Imagine there are 200 dragons, 5 of which are golds.The ratio of golds to total dragons is now 5:200 = 1:40. If the target ratio is 1:50 then prices will be higher to compensate.Now imagine there are an extra 200 dragons added, none of which are golds.The ratio would then be 5:400 = 1:80. Then, assuming the same target, prices will drop.This is of course simplified, and the ratios may not work like this, but this matches observed behavior pretty well.
gollark: That why was rhetorical.
