Allosaurus fragilis

This is the very first dinosaur picture I drew using actual reference that wasn't either a model or from JP. I did this way back in 2000 for Prehistoric Times. This is what sparked my interest in drawing dinosaurs, and while the style might be a little off from the norm, there are other comic book pros that have also delved into the world of dinosaurs, Art Adams, Ricardo DelGado, and William Stout. I've heard rumors that Walt Simonson also draws dinosaurs, but I have not been able to find anything else about that:( Now on to Allosaurs:

This was the first large theropod described, there have been several subspecies attributed to it, Atrox, Maximus, as well as similar animals that might be sysnonomus with it, Epantaris, Saurophaganax. The Fragilis skull is now thought to have been restored incorrectly, so since it was named first Allosaurus atrox has been lumped into Fragilis. Likewise Epantaris seems to just be a large adult individual so it too seems to now be lumped into Fragilis. As for Saurophaganax A.K.A. Allosaurus Maximus? An unpublished analysis appears to place it as an early Carcharadontosaur and therefore not a member of Allosaurus, just closely related.

The first picture has some flaws, the arms on but the main allosaur are incorrect, some of the anatomy is off, but for a first try it still holds up well. At the time of this drawing the feathers were entirely speculative, but recent finds might actually prove this drawing feasible.

Allosaurus is a medium to large theropod from the late Jurassic, we have lots of specimens, from small to large. Maximum size would be somewhere around 40 feet with a 3+ foot long head. Sometimes referred to as the lion of the Jurassic... but they most likely would be better compared to wolves, they have smallish teeth for such a large animal. They've found many of them fossilized together in large bone beds so they were most likely pack animals, I find it hard to believe all dinosaurs lived solitary lives.

That's all for now,



  1. Now, I have two Brett and Jess blogs to follow.

    Work for Google Reader!

    Best wishes on both blogs!

  2. Hi Brett

    Well, I suppose here's just the finest place to write about artistic palaeoart 'reconstructions' and other stuff like these. Being involved on that "DA connection" is just a shame for palaeo-fans [though I'm not an expert on palaeoart-topics and DA policy].
    I'll link this blog on "Geomythologica".

    Best wishes for the "Carnosauria" project.
    See you soon


  3. Dear Brett,

    The hypothesis that Saurophaganax is a basal carcharodontosaurid is not based on a published study. I cited it in my blog, but note that it is derived from on preliminary unpublished phylogenetic analysis that I'll(hope to) publish soon.

  4. For some reason these are not showing up in my email, I'll have to fix that:)

    Hi Nestor and Ezequiel!

    Hi Leo,

    I'm going to try and start a blog linky thing, I'll be sure to add yous:)


    Thanks for gracing the blog:) I do know it's not published (I haven't seen the paper mentioned on DML) and have changed the text to link to your blog for the info. Sometimes what I'm thinking and what I type are two different things, I guess it wasn't speculative enough:)

    I'm not a 'wait for the paper' sort of guy myself at least for the drawings and tend to get ahead of myself. But since the carcharadontosaurs are sort of my favorites I could resist drawing or mentioning it:)



  5. AWESOME!!!!!!!!!! Feathered allosaurs!
