JP-Expanded SB Gryposuchus by Teratophoneus JP-Expanded SB Gryposuchus by Teratophoneus
As promised, I continue with the jp expanded series

Name: Gryposuchus croizati
Length: up to 11 metres
weight: 1,75- 2 tons
Time: Early Miocene
Agressiveness: 25% not agressive
Dangerousness: 70 % Dangerous!

Gryposuchus is the biggest gharial ever and therefore it cant be excluded in the parks list. This animal, despite its frightening appearence, is mostly a gentle giant. Like its modern counterpart, this gharial eats only fish and small animals. Gryposuchus has needlesharp teeth in its elongated jaw. These teeth can cut a fish in half, hence its codename cutter, for its behavior to cut easily to its prey items. Gryposuchus males are bigger than females. Unlike many other reptiles cloned for inGen, this animal isnt in the reptile house on the second island of the park, instead a paddock was built around a swampy river terrain of one of the second islands rivers. This river is near the reptile house and has swampy areas as well as more clear ones as Gryposuchus prefers both. inGen files show that this animal lives mostly in the water and is active mostly in the evening. During the day, they can often be seen lying on the river banks , opening their big jaws to cool themself. SO far 5 Gryposuchus have been breeded, one male and 4 females. These re already on the island and are one of the big attractions of the parks second island. As said, this animal eats mostly fish and they are feeded one time a day by the keepers although they also hunt the normal fishes which live in their habitat anyway. These feedings are also though to become a public magnet. Gryposuchus produces hissing sounds and our male already shows the ghara on the end of its snout. Although not very agressive to humans, they can be very dangerous as the females protect their nests. For that they not only use their jaws, their tail is extremely powerful and can easily kill a human with a single blow !. One keeper had to find this out on Isla sorna as he came to close to a nest and got a painful hit with the tail of a gryposuchus female. 2 broken ribs were the result of the hit. Gryposuchus was cloned before isla sorna was abandonded. Although they were bred under the sb program, they can be found on Isla sorna in the wild and also on Site C. Gryposuchus doesnt wander into the ocean like the modern saltwater crocs, gryposuchus is a completel fresh water based animal. They are elegant but also very powerful swimmers and if neccesary the can quickly come out of the water. Gryposuchus´feet carry swimming mebranes which are the biggest of an of our bred giant crocs. Although its was cloned quite early, not very much is known about the behaviour of this giant, probably because they are masters of disguise. Keepers like this crocodilian as it isnt as dangerous as some of the parks other crocs like deinosuchus or purusssaurus which are also set to be included in the park. It seems that gryposuchus gets along with purusssaurus. This is probably because they lived together in the miocene in the same area and prefeed different feeding styles. They dont compete with each other as found out on Site C were a small purussaurus population is present.

Note: I actually studied modern crocodile paddocks in zoos to draw a natural environent.
Note 2: Yes it isnt coloured. I am not expereinced with colouring crocs and I need someone who can digitally paint it. It would be very nice if someone could do it and make a badass pic out of it :D
Everyone who wants to can do it, just sent me a link to the finished one. Would be cool if it would look more or less like a modern croc in terms of colouring because the prehistoric crocs probably didnt look different in colour like the modern ones
I hope that some people will respond :)

To get a better idea about the weight, just take a look at this size comparison: [link]
The saltwater crocodile at the bottom of the picture would already weigh around 1000 kg at 6 m. Gryposuchus would be around 60% longer and weigh probably around 4,5 times as much or even more.

Very nice drawing! However I have to note the real weight of Gryposuchus was surely much higher than 1,75-2 tons, and more probably around 4-5 tons. I know the paper in which the weight was estimated by certain cranial measurements, but I totally disagree with the results. Postcranial anatomy of amphibious crocodylian is extremely conservative, so Gryposuchus surely didn´t differ much in body proportions from other crocodylians. So we can estimate its weight much better by comparing it with crocodylians of known weight and length. You have to keep in mind that already the very largest modern crocodiles already weigh around 1,5 tons or more (of course this are extremely rare exceptions), so it doesn´t make much sense to assume a crocodylian 50% longer would weigh only slightly more.

Great work! I like specially the head :)

thanks a lot. I actuall used the head of a modern gharial as reference . The fossilized remains werent "clear" enough for me to draw it like that so I used itsmodern relative :)
