The Brett Booth Dinosaur Blog, dealing with pointy teeth on bitey things.

Deltadromeus is now thought to be a noasaur, off the abelisaur family tree. From Africa, it's another really big theropod around 40 feet. But this one is differnent, it's very gracile, built for running. The head is based off of the other known noasaur species and might be incorrect, it's a best guess at this point.
Being an ableisaur it's strange in that it has long arms and is larger than any of it's other known relatives. I beleive Carnotaurus would be the second largest at around 25+ feet. So this animal was a giant for the group. It's theropod contemporraries include Carcharadontosaurus and Spinosaurus, also giants, so there seems to be a trend of giant theropods in mid cretaceous Africa. There are a few other large theropod remains fond at the sime time and same area but they are too scrappy to make good identifications. So perhaps there is a fourth group of large theropods running around Africa that we don't really know about;)
Brett is a comic book artist currently working on nothing he can mention, damn it! He also draws dinosaurs! He likes to talk about science and evolution if you don't want to here about that stuff, tuff cookies;)
If you would like to use my images on your web site, please e-mail me. (brettbooth at gmail dot com) I usually grant permission for non-commercial uses but I do require that you provide a link back to me. If you are a scientist, or represent a museum or educational institution, one time print use of dinosaur images is very low cost and sometimes free, please inquire.
I am happy to draw original paleo artwork for papers, articles and the like. I'm happy to do these for very reasonable fee's and in some cases I'll even wave that. So feel free to ask.
I will no longer doing comic/anthro character commissions. See other blog.
