New Dinosaurs

[fj8e5la]

The Allosaurus displayed was the first dinosaur I copied with zbrush after having seen a real skeletton at a natural history museum, over a decade ago. Compared to
yesterday presented lean or even scrawny shaped Tyrannosaurus, it is anatomically more correct. Here, I noticed the skulls of living appearence reconstrucitons to be longer than
their fossile exemplar. A detail influencing this model. The Allosaurus shown is not fully grown, as it can reach supposed sizes up to 12 meters of body length, same as
Tyrannosaurus. In order to adapt to a common illustration style, it is using red colors.



All the models shown are derived from Poser 5 content figure "Raptor" because I was not able to import and adjust zbrush and PSD created textures on my own models into
Poser 5. They would appear in a random placed pattern, not applying to the body parts, they were created for. The skins are fully posable but when twisted to a certain
degree break or morph to an ununsual shape. I have done some detail work in photoshop.

Derived form Poser 5 model "Raptor", the arm position on T-Rex is not anatomically correct. But the images now shown will render possible, that it's head is as promised
based on real skull photography.


Velociraptor mongoliensis very low poly scaled model. I did not add feathers because of the complexity of bone structure.

This is a Baryonyx walkeri scale model.


Carnotaurus sastrei but still using a false bumpmap. Lack of time. Sorry.


Plant eaters will follow.

Baryonyx Walkeri and Carnotaurus sastrei are derived from illustration, not from a real skeletton. So I can not grant them to appear anatomically correct.

[fj8e5la]

first, I have to correct some mistakes:

Allosaurus was mentioned to appear anatomically correct. The arms are a bit stretched, a morphing side effect from twisting them in software Poser 5 without
right morph settings.
Velociraptor mongoliensis did not have a long neck as shown on last week´s image. The following illustration will show a better reconstruction:

This image shows a Velociraptor mongoliensis compared to Deinonychus antirrhopus. Deinonychus antirrhopus grown to 2-4 meters in length,
was named Velociraptor in motion picture Jurassic Park:

Some members of Tyrannosauridae: (left to right) Alioramus remotus, Albertosaurus libratus ans Tyrannosaurus rex, this time added a bit more flesh:

Albertosaurus sarcophagus now has a 3d-skin on it's own. Compared to last time's 3d-skin using an Alioramus remotus head scaled to Albertosaurus sarcophagus' size, the following images are based on a low resolution bone photography. I did not have different angle view photographs but it resembles more of what is displayed on the
photography:


Some Tyrannosauroidea (left to right): Alioramus remotus (possible juvenile Tarbosaurus bataar), Gorgosaurus libratus (or Albertosaurus libratus), Albertosaurus sarcophagus, Daspeltosaurus torosus, Tarbosaurus bataar (or Tyrannosaurus bataar) and Tyrannosaurus rex. The specimen shown resemle information available regarding skeleton photography(I especially paied attention to reconstructing the teeth' look):

Scaled models of largest known carnivore species in taxonomic family (left to right) Spinosaurus aegiptiacus (spinosauridae), Giganotosaurus carolinii (Allosauridae, paleontologists suppose an even bigger species named Sacrophaganax maximus but it is only based upon a single vertebra) and Tyrannosaurus Rex (Tyrannosauridae):

some scientists assume Spinosaurus aegyptiacus' vertebra dorsal extensions were not surrounded with a skinny sail for heat control. The dorsal structures possibly
carried large muscles, that helped to stabilize the Dinosaur when leaning forward for e. g. fishing. The illustrations shown visualize this therory, comparing club-shaped extensions on a drawing of Spinosaurus aegiptiacus' skeleton to those found on Dimetrodon's skeleton. A scaled illustration of Spinosaurus aegiptiacus and Tyrannosaurus rex:

Scaled image of Giganotosaurus carolinii, resembling a first attempt to visualize a life image from a single bone photography, I found in the internet. Here, the entire skeleton was not displayed and only shown from perspective so the anatomy is just a suggested dinosaur that was even a bit larger than Tyrannosaurus. Reported is a skull longer than the height of an average human male:

I did some changes to the agile reported Carnotaurus sastrei after having seen a photography of it´s skull:

Baryonyx walkeri built from a skeleton reconstruction photography:

Cryolophosaurus ellioti (from Dilophosauridae):

Ceratosaurus nasicornis (but not as nicely done as the model shown in TV-series "jurassic fightclub":

Gallimimus:

An improved model of Stegosaurus armatus with a proper work at the legs:

First attempt to visualize Brachiosaurus brancai looking for the right proportions:

Edmontosaurus annectens:

Hypacrosaurus (Edmontosaurus model with just a few changes):

An attempt to build a Stegoceras from skeleton. The skull photography was only available in side view so the portrait view most likely differs. I did not add fingers and toes in this early stage:

Styracosaurus albertensis, now showing some anatomical improvements at the legs compared to last series included Triceratops horridus reconstruction:

Black parts of some images resemble posing error correction.

Here is some new analysis of Tarbosaurus bataar and Tyrannosaurus rex (left to right) based on "skulls compared" (Hurum & Sabath, 2003).
The models shown are same polygon resolution but differ in shape from the 3d skins shown before.
Unfortunately, I am not able to work with a higher resolution. Insufficient memory.
Regarding "Jane" (or "Nanotyrannus") which some paleontologists consider to represent a juvenile specimen of Tyrannosaurus rex, I worked with a slim skin to illustrate
the adult Tyrannosaurus rex. Anatomic differences reported, tend to seperate the genus Tarbosaurus from genus Tyrannosaurus.

Allosaurus in first posted image is fully grown scale.

If your aiming for accuracy....add scales or feathers to these suckers...and please rotate those palms inwards so they face each other...The dynamics of the therapods wrist bones simply would not have allowed them to do the "jurassic park" dangly hand thing.

[bobzilla]

These are pretty neat, but they don't look very accurate. The stegosaurus has way too many plates and the sizes are all off.

They are nice models, but anatomically, they all look just a little...off...

[ministerart@hotmail.co.uk]

here you go bud...if you want to see some quite comprehensive monographs of the latest findings..e mail me...get those hands rotated....down with Jurassic park.

[a i r]

These are all good bases for further work, but none of them looks finished, and you got lots of inaccuracy going on to, as guys before me suggested.
Keep pushing it, don't get discouraged by our critics, it's just, you seem like you love dinosaurs and stuff, and seems like you have potential to take it few levels higher..

take care!

That was something I was wondering about... I supposed T Rex' hands to face downwards if getting trapped with it's teeth by biting between two bones. Did all of theese species have feathers?

yes, Stegosaurus I recognized to have more plates but I just placed some dummies. The legs' had false proportion on the frist image. That's where thoose crinkles came from.

I am not used to paleontolgycal anatomy. There are some improvements on second Stegosaurus' legs. Dinosaurs just resemble a way to post something reconstructing a topic that can not be shown by a skeleton or is related to any existing entertainment industry. Thank you for your critics.

[fj8e5la]

Hello to all of you.

I am now answering a second time because I was not able to translate the words "neat" and "dangly" as I am, as you might have noticed, not a native speaker and not used to speak English regularly. I apologize for my bad linguistic attainments. Our national zbrush board is a very low skill level board, as far as I have reviewed the image and contest galleries (my critics, as you can see...) where this thread would not fit into. So I posted at zbrushcentral.

Regarding anatomy, I had to look for some upper and lower thigh ratio on Stegosaurus' legs. That was a major mistake, I intended to correct with beeing more or less sucessful on the second image. The amount of dorsal plates is intentionally done wrong by placing less structures in random sizes and shapes.

I am espesially glad to have my posted images being chracterized as "neat". Allthough they are ...off

This again is a scaled view of Tarbosaurus bataar and Tyrannosaurus rex based on some skull photography of Tarbosaurus. But it might be a replica as it
is a really characteristic skull with a high snout that differs a lot from regular Tyrannosaurus. I only found those maxillary owl-shaped bone rings around the orbital fenestra appearing in all Tarbosaurus skulls. The palms are now facing each other:

The tyrannosauroidea image is using new 3d-skins:

The Edmotosaurus painted in zbr 2.0:

Here is an Edmontosaurus and what is happenig when importing into poser5:

This texture map, as shown below, not only applies to the body but also to the legs:

my texturemap:

Same error appeared on .obj file "troll" provided on www.pixologic.com.
Can somebody help me with this?

[locusta]

First, may I ask You why You still use Zbrush 2.0? You know that You can upgrade for free?

Second, You have to swap your texturemap before exporting. It look wrong then in ZB, but right in other 3D application. Must be swapped the V.

Hope it helps You.
