Looks kind of like a piece of the sail is missing; Sail may have been for display or species recognition, or thermoregulation or for storing energy ... (because of non-serrated teeth and its vertebrae being similar to Sigilmassasaurus) ... And since all modern birds have ZW genes, it’s likely that non-avian dinosaurs did … Sigilmassasaurus was basically a different version of Spinosaurus. They both belonged to the same specimen and while controversy may be arising tow... Introduction. After having read the Jack Horner's book "The complete T.rex" I remember to have been in total disagreement with his theory i.e. That'd take some of the 20 tons off its legs. It's thought that the sail might have served multiple purposes from helping with thermoregulation, to make the animal appear much larger then it really was (remember that Spinosaurus and Sigilmassasaurus still lived alongside behemoths like Carcharodontosaurus), help speed through the water like the sail of a marlin, and possibly an anchor point for to help with powerful tail movements. Liopleurodon. Nearly 3.5 m (12 ft) high at the hips, B. tenerensis may have waded into rivers and lakes like to catch fish, but probably could swim in deeper water as well, using its back legs and possibly its tail for propulsion. It had paddle-like feet and nostrils on top of its crocodile-like head.This would let it submerge as a crocodile does. The explorer Christopher Columbus made four voyages across the Atlantic Ocean from Spain: in 1492, 1493, 1498 and 1502. This small creature is the direct descendant of modern horses today. The animal everyone thought was 25 meters long, but in reality only is about 7 meters in length, since the fossil of its head was estimated to have been a fifth of its body length. There even seems to be some indication that Sigilmassasaurus might be the larger one too. 140+ Full Sail Grads Worked on This Year’s Oscar-Nominated Films. The acceleration also depends on its distance from a light source and strength of the light source. It was named and described by Ronan Allain and his colleagues in 2012. The authors also suggested that the deep tail may have also have helped stabilize the animal and prevented it from rolling onto its side whilst floating (Ibrahim et al., 2020), similarly to a proposed use for the dorsal sail a few years prior (Gimsa et al., 2016). It was one of the largest known carnivore theropods, as well as being a candidate for the largest terrestrial predator. Alternatively, the sail - in conjunction with the crest - was probably used for display, regardless of other possible functions. I prefered the Robert T. Bakker's depictions which were revolutionary. Silvisaurus - This primitive nodosaur was discovered in Kansas. Is Spinosaurus still the largest theropod?

This is due to the fact that a paper written by Arden et al, saying how MSNM v4047 is actually not Spinosaurus, but belonged to Sigilmassasaurus. T... May have used its long narrow tail to stun prey like a thresher shark; Sailfish herd schools of fish into a “bait ball” and trap the fish so they can snatch them with their bills (use as a screen to encircle the prey) Dorsal sail would help with sideways movements of the neck and tail, like sailfish and thresher sharks It is uncertain of the function of this dinosaur's sail or hump, scientists have proposed several different hypotheses including display, and heat regulation. Also, have you considered that a density of 1 or more is still possible, even with airsacs, because most tissues as a whole are denser than water?'' Sigilmassasaurus brevicollis. I think it would be cool if this creature was implimented into the game don't you think?
