Hi everyone! As I have mentioned several times, being a 3D artist I am trying to move into the field of paleoart. Recently I have started modeling Ceratosaurus nasicornis in 3D, and I really want to make it as accurate and plausible as possible. Here is what I have got so far: a basic model done in 3ds Max. After this I am planning to take it to ZBrush and add more muscle definition, sking wrinkles, scales and other fine details. At this stage this is just the base and I would like to share it with you guys in order to receive some feedback from those who know their dinosaur anatomy. Did I get the shape and overall structure right? Constructive criticism is more then welcome, pretty much this is what I am asking for here. 1. Mesh 2. Body 3. Perspective 4. Back 5. Top view 6.

Is ceratosaurus dentisulcatus the biggest known of its species ? would its tooth be different from its other species tooth length,size and serrations ? is there any difference between magnicornis and nasicornis ?

Some of you might remember my other thread in which I collected a group of Cretaceous marine predators. It was a process that took 3 years > http://www.thefossilforum.com/index.php?/topic/48360-predators-of-the-cretaceous-seas-teeth-set/ Now I'm ready to begin my next collection, but first I need to gather some info to see if this is even a viable endeavor. As thread title suggests, I'm going for theropods this round. The commonly seen ones like Nanotyrannus, North American Tyrannosaurs etc I'm not too worried. It's those big four in the title that has me wondering if I can even complete this. Has anyone seen them anywhere?

Ceratosaurus is one of my favorite Jurassic theropod Dinosaurs found in the Morrison Formation. Teeth of this and other theropods are commonly sold through online Dealers, Auction Houses and at Fossil shows. Just because a site/dealer sells Jurassic material does not guarantee accuracy. . Variation of the teeth in the jaw also adds to the complexity. Isolated teeth from the Morrison Formation are very difficult to diagnose and all require an understanding of additional characteristics than normal, in hopes of properly identifying them. I have not been able to find any publication that describes the teeth of this species, other than anterior ones, so it's beyond me how Sellers identify them. The best I can do is to look at other reference publications some which include similar teeth from Portugal and Germany which describe morph types and then assign them to the best taxon. So until we have a better definition this is a start to get us in the right direction Sellers need to provide you the following information: 1)Photo of tooth and one of the mesial edge 2)Serration density of both edges, 5 mm wide at midline 3)Dimensions: CBL, CBW, CH 4)Locality: State and County Premaxillary & Anterior teeth of Dentary Tooth: CHR : 2.47 - 3.56 Crown height ratio CH÷CBL CBR : .92 - 1.43 Crown base ratio CBW÷CBL Mesial Density: 19 per 5 mm, Distal Density: 11.5 per 5 mm all at midline, DSDI > 1.2 (Denticle Size Density index) Cross-section base : Subcircular Lingual grooves (flutes) are diagnostics and on the lingual side only. Gooves are only present on premaxillary and the anterior three teeth of the dentary. Lateral teeth Tooth: CHR : 1.54 - 2.86 Crown height ratio CH÷CBL CBR : .32 - .5 Crown base ratio CBW÷CBL Mesial Density: 14 per 5 mm, Distal Density: 14 per 5 mm all at midline Cross-section base : very compressed oval Mesial and Distal carina extend to the base If you would like to learn more about Ceratosaurs, bones and teeth there is a great soft covered printing. Ceratosaurs (Dinosauria, Theropoda) A Revised Osteology by Madsen and Welles by the Utah Geological Survey Its also available on PDF but the book is cheap and a great reference guide. If anyone has additional information to add to this please post it. Reconstruction Skull of Ceratosaurus from Utah Museum of Natural History.
