Deinocheirus by Hyrotrioskjan
Deinocheirus
Again here two small, quick paintings of an recent "discovery".
Finally after all that waiting Deinocheirus steps into light, not really surprising stuff (beside the thickness of the lower jaw and the fragments of fishes in the stomach region).
NatGeo gives a good overview here: phenomena.nationalgeographic.c…
And the Nature paper can be bought here: www.nature.com/nature/journal/…

This is not my first try on Deinocheirus, shortly after the last SVP meeting I produced many sketches and a painting based on descriptions: <da:thumb id="411584297"><da:thumb id="412704181">

Two idea I want to share.

I'm still deep inside the four-dimensional matrix of northern Africa, especially the Bahariya formation. Since working on Jurassic Germany I always try to get a whole picture of an ecosystem, so I also read about the crocodiles, the invertebrates and even plants of this formation (many water-plants, inter alia a mangrove tree-fern) and of course the other dinosaurs.

Interestingly very little is known about the herbivores of this time at this place, most likely because there were not many of them (a observation also made in Kem Kem) ornithishia are even completely absent. But on the other side we have remains of giant Theropods like Spinosaurus, Charcharodontosaurs and Deltadromeus (which is a very controversial fellow). 
Spinosaurus was maybe a bit like a mixture of polar bear and heron, swimming from shore to shore and from mangrove island to mangrove island to hunt large fish in the shallow waters (or, how some assume, drifting motionless in deeper water until something tasty swims by). And how I showed already in my gallery, the waters of northen Africa were filled with fishes and other animals large enough to fill the stomach of even the largest spinosaurids.
The diet of Charcharo seems to be different, teeth, skull and body were more conservative, good to cut through flesh but not really helpful to grab fish. Here the sauropods of Bahariya comes into view, represented by two species, Aegyptosaurus (Stromer 1932) and Paralititan (Smith et. al. 2001) (and maybe also Rebbachisaurus).
OhSoSocial Apex Predator Behaviour by Dinofuzz
Aegyptorsaurus was a middle sized sauropod, maybe 16 m long while Paralititan was much bigger, maybe 26 m long giant. Both species are, though they were large (and large bones are more likely to be preserved) only represented by one specimen, and the Aegyptosaurs bones got lost during WWII. 
When we look at this graphic Bahariya, Egypt by NamDaotetanurae it becomes clear that Charachrodontosaurus was not larger than Aegaptosaurus but definitely a big danger for this sauropod. 
Of course we don't know for sure that Charcharo hunted these animals but when we look at the known fauna of Bahariya it becomes clear that there was not much else which would fit it's jaws. So the question is: how could Aegyptosaurus withstand such attacks. Because of the teeth I would suggest that Charcharo tried to cut large pieces of flesh out of the hides of its prey, stood back and waited for the next opportunity. One possibility would be to live in herds, and maybe Aegyptosaurus had osteoderms like some other titanosaurs which gave it a bit protection. Another thing which came into my mind is multi-species herding. Adult Paralititan were definitely too large to fear a Charcharodontosaurus, maybe even several of them. Like some modern herbivores Aegyptosaurus could walk together with their larger cousins to get protection. Thanks to the very different sizes (and maybe other attributes) both wouldn't rival much*.
It's also possible that sauropods like Aegyptosaurus were just seasonal guests of the Bahariya river systems. Maybe they migrated toward the north in the dry season when these regions still had enough water to feed Spinosaurus with fish.

On a side note I think it's also possible that Charcharodontosaurus sometimes used fish or crocodiles as a source of proteins. With so many aquatic creatures around it would be strange if not.


*Idea for Paleoartists, maybe Aegyptosaurus even looked similar to adult Paralititan


Well these are mymusings for the day, make of it what ever you want =)

Paranogmius doederleini by Hyrotrioskjan
Paranogmius doederleini
This is, for now, the last part of this series.

Recently was able to get my hand on one of Stromers original writings about the Bahariya formation with one chapter about the gigantism he observed among the animals he discovered there (he also asumed that many of the larger theropods were probably piscivorous). Paranogmius was only known from very large, compressed vertebrae which made it impossible to identify this lost giant (and like most Stromer material these are now destroyed). I googled the taxon but found no new information. But the next day, while searching for another species, I found a page with 
Concavotectum kerchak.com/dinosaurios-y-otro…
How it turned out Concavotectum (from Kem Kem) is maybe conspecific with Paranogmius and both are members of an extinct, very diverse group of teleost fishes, the Tselfatiiformes. Based on their general appearance and the skull of Concavotectum I try to reconstruct these fishes for the first time. 
Based on the size if Paranogmius' vertebrae this monster was even a bit bigger (this specimen is 3,5 m long, the Bahariya specimen was maybe 4 m long)

Schizorhiza stromeri by Hyrotrioskjan
Schizorhiza stromeri
Well, here we go, another part of the Spinosaurus snack series (I call is SSS (or just ß?)) 
Not Onchopristis, but a smaller relative, Schizorhiza, a sawfish from Bahariya and the Kem Kem beds with an very unusual saw (take a look! biblioweb.tic.unam.mx/libros/p… ). Not visible here but I decided to make them all in lateral position so I WILL NOT CHANGE IT NOW!

Schizorhiza was maybe a bit too small for adult Spinosaurus but juvenile and subadult animals would certainly love these fellows, especially because of the little saw-teeth, lets say it was baby food, and Onchopristis is the real meat!

Finally, after some months of waiting the german TV release a small spot about me and my work, my voice sounds a bit strange and the moderator calls one a dragon a dinosaur (it was a Diratherium!) but the rest is fine ^^

See me in action and saying silly things because I had not much time to think about it (in german only):  www1.wdr.de/mediathek/video/se…

Hi, my name is Joschua Knüppe

In the moment I study free art at the Academy of fine arts Münster and I hope to work and teach one day as a independent artist and illustrator.
My work can be split into three big parts:
1. Paleoart and Paleontography
2. fictional ecosystems, some of them on other planets
3. mythical creatures, especially dragons, depicted in a realistic way

All my work is connected together and form large four-dimensional networks which become more and more dense with the time.
In terms of an classic modernist I'm a concept artist, which means that the idea is for me always more important or interesting than the form of it, I still try to improve myself, and I see that it work, but the construct, the concept behind my artwork is the real art.

I love comments, positive and negative, try to reply each of them and 'm always open for questions.

Projects which are belong together and form large four-dimensional networks:
-Part time humans
-Dragons of the world
-Silvanus
-Wegener 2
-Serentopia
-Atzlan
-Future birds and their world
-Organic technology
-Paleoart (with Jurassic Germany and many more)

Out of this I have two other projects:
-Pyrungata
-GDM (Global Dinosaur Monument)

This ID cards have a place for interests and hobbys but I'm interested in too much things so I count them here:
dinosaurs, pterosaurs, mosasaurs, birds, dragons, art, art history, paleontology, walking, annoy creationist, writing, reading, drawing, painting, working with clay wood and metal, ants, biology especially behavior, bio technology, bio informatics, fantasy, SiFi, being at DA, doing exhibtions, holding lectures, arguing and many more.

Well, take a look at my Gallery maybe you find something, beautiful, strange, interesting or more positive adjectives ;)

Copyright:
If you want to use my work ask first, I normally don't mind but I want still the controll over my work. Also I don't like to see my work out of it's original context, how I said: the story behind the pictures is important!

Commissions: I normally don't do commissions, exeptions are for scientists who want a reconstructions. In addition I do sometimes sketches for friends and people who ask friendly =)

Contact:
If you have questions or other reasons to contact me can send me a Note here on DA or mail me under: utahraptor.jo@web.de

I'm now also on Facebook! www.facebook.com/pages/Art-by-…

Mit dem Diadectes muss man ihm aber auch recht geben. Überall grün! Wie ein riesiger Leguan! Argh!

Aber der Schleimaal war ja auch mal genial! :D Neunaugen künstlerisch recycled!
