Tylosaurus - teach the controversey web resolution by ScottHartman 

First of all, let me thank all of you who wrote birthday well-wishes, all of the wonderful social interactions on DA are what keep me coming back. I also wanted to update you on a blog post I wrote about mosasaur tails: www.skeletaldrawing.com/home/m…

The tl;dr version is that you can still find people who would support any these extremes in tail fluke design, but I think the middle two (or somewhere in between) is the most likely. Hit up the article for more depth as to why.
Tylosaurus pembinensis by ScottHartman
Tylosaurus pembinensis
The giant Cretaceous marine lizard Tylosaurus. And yes, they're really just lizards, not some exotic extinct group like plesiosaurs or ichthyosaurs. The most recent studies place mosasaurs near snakes (which are also lizards, so please stop saying "lizards and snakes"), although previous studies have placed them closer to monitor lizards.

Anyhow, I couldn't decide between the closed mouth pose, which I find more aesthetically attractive and would have been a more common life view, and the mouth-agape-feeding-and-looking-badass version that better shows off the teeth. So I did both. For those of you who haven't kept up with recent revelations with mosasaur soft-tissue, it turns out that they had tail flukes and stiffer bodies than previously thought, swimming more like a shark than a giant sea snake as has been depicted in the past.

Edit: Updated the sternal elements, made some changes to the articular angle of the chevrons at the tail bend, and also updated the tail fluke to a slightly more contemporary interpretation.

Call me...Sea Lord! by ScottHartman
Call me...Sea Lord!
It's not Chris Pratt, it's Thalassomedon! It's mostly in a swimming pose, but it wouldn't normally swim with its mouth open (unless maybe it had bad breath).

Ichthyodectes - the fish mouth by ScottHartman
Ichthyodectes - the fish mouth
This is a large (4m) long predatory fish from the Late Cretaceous. It's related to Xiphactinus, an even larger (~6m) fish that is probably more famous.

On a side note, this skeletal really made me hate fish. Soooooo many ribs and vertebrae, and the first half have accessory processes that interleave with one another and the neural spines. It's seriously demoted teleost skeletals to somewhere around the level of armored dinosaurs in terms of obnoxiousness.

Monovuuia? Shuvonykus??? by ScottHartman
Monovuuia? Shuvonykus???
This is supposed to be Mononykus, but like everyone else I had to use the skull, mandible, and tail of Shuvuuia and pelvic data from other alvarezaurs to fill in the gaps. The pectoral girdle does not look as advanced and horizontal to me as others have restored it, and the preserved anterior dorsals of Mononykus seem to have a slight upturn to them (not unlike ornithomimids). 

P.S. Yes, it really is that long-legged and small-footed. Strange, eh?

Hey Scott,
Do you sell your prints? If so, how do I go about ordering them and what size does the prints come in. Thank you so very much ~ I have been your fan for so many years

Alas, outside of a couple that I have enabled here on DA I don't currently sell any prints - I'm really bad at this monetization thing apparently.

Hi there. I'll be doing a talk on my work and on paleoart in general with these guys, PechaKucha Colombo, and I'd like to use one of your skeletals in the presentation I'll be doing then. I'll get you the link once I'm done :) and all credit shall be given to you...

Hey There Scott, I thought you'd be interested in these,
saurian.maxmediacorp.com/ (Saurian)
www.dinosaurbattlegrounds.net/ (Dinosaur Battlegrounds)
Two groups of game designers and programmers have set out to making dinosaur simulators using the most recent paleontological data, both groups are focusing on the Hell Creek formation and so far they've made significant progress! feel free to check 'em out. :)
