I was going to try and get some actual reference for this one, but I could find none. I know I've seen some skull remains somewhere but my web-fu was not up to the challenge. Andrea Cau of Theropoda has proposed that this guy MIGHT actually be a late surviving carcharodontosaur, so I drew one up and added a quick tone. This is COMPLETELY hypothetical!!
Sorry for the slow posting, I've been busy. New stuff soon:)
Been a bit busy, so no time for anything major. Here's a hypothetical drawing of the hypothetical/mysterious Tyrannosaurus X. A possible gracile tyrannosaurus, that some believe is a separate species from the traditional Tyrannosaurus rex.
I'll try to get more in depth when I get a chance to color this up. But I'm trying to finish off these pages, start a new project, and draw a skull restoration:)
Sometimes the best stuff has already been dug up. Recently an old specimen (considered a sub species of Chilantaisaurus) has been re-examined and found to actually be a member of the carcharadontosaur family. So it's been renamed Shaochilong maortuensis.
This is the first instance of a carcharadontosaur in Asia. It's know from pretty scrappy remains and might actually turnout to be a juvenile, so this drawing it pretty hypothetical. The cool thing is that these animals might have actually feed on primative ceratopsians and competed with early tyrannosaurs.
Sorry it's not in color, but I just finally got it scanned! A Suchomimus catching a young plesiosaur.
A few years ago I was asked what I thought of the swimming Spinosaurus idea (I was told this was put forth by Robert Bakker but I've only heard it mentioned a few times so I have no idea.) At the time I said I found it unlikely, at least for Spinosaurus, the sail would be a hinderence in the water, waves would topple it, the local crocs would eat it for lunch as they were far more adapted to the water, yadda, yadda, yadda. I didn't really look into it, I knew spinosaurs seemed to found close to water, and that they would eat fish (fish scales found in the stomach area of Baryonyx) but that's all I had read about swimming spinosaurs... until a few months ago.
Other than the scene in JP3 most of the spinosaur pictures show them wadding out into ankle deep water looking for fish, like some giant egret or stork. Since spinosaurs are so poorly known and fragmentary it's very difficult to get an idea about what they might have been doing, why did they get to big? Spinosaurs has been said to be 65 feet long dwarfing every other theropod, that's at least 17 feet longer than the next largest theropod (this is highly unlikely but is found all over the web. They were more likely similarly sized to the other large theropods, perhapse a bit longer but more gracile.) Did they eat fish exclusively? A spinosaur tooth has been found embeded in a pterosaur bone, along with the fish scales in Baryonyx's stomach were the remains of an Iguanadon (so the answer to that would be no.) How did they behave? Questions upon questions that we'll most likely never be able to fully answer.
I stumbled upon this site looking for skeletal reference: spinosauridae.fr.gd (This is the English translated version, its really easy to read so don't let the translation stop you!)
On the site are papers, drawings and pretty much the best place to go for info on spinosurs on the web. As I read the papers cited, and looked at the images, the site was trying to tell me something. The papers mentioned isotopes from spinosaur bones are more in line with crocodiles and animals that live in an aquatic habitat, foot print traces of swimming theropods... this site was arguing FOR semi aquatic spinosaurs. I spent a few hours looking everything over (I'd go over specifics some, but I can't get it to load properly, my computer has bogged down, but go read it for yourselves!) And while I think more finds need to be located, it's very compelling stuff. Semi aquatic spinosurs... cool!
A few months ago a new paper described a fossil impression of a sitting theropod. I had actually drawn a reconstruction of the beast months before, based on footprints from the area, known to some as the St George theropod. It's entirely speculative, but since there is no actual skeleton associated to the footprints, it's hard to say who the footprints actually belong to. It could actually be one of a number of known species but in this case nothing official has been named. So this is a hypothetical image of the track maker and below is a shot of the position it was in while sitting. For this image I actually chose a theropod that I had not drawn before, so this is a Liliensternus inthe resting position. Note the strange position of the front legs/arms, Freaky!
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.
