“Spine lizard”
Early-late Cretaceous, 112-97 million years ago

Spinosaurus was big. Very big. The-longest-flesh-eating-animal-to-ever-walk-the-earth big. Even based on more conservative estimates of about 49 feet in length, it readily beats Giganotosaurus, Carcharodontosaurus, and Tyrannosaurus rex. And according to new research, Spinosaurus was also an able swimmer, snaring prey on land and at sea with its slender, crocodile-like jaws. Scientists have previously proposed that its elaborate sail was used for thermoregulation or sexual display, but based on its newly revised, almost quadrupedal stature, it is now widely accepted that Spinosaurus was just desperately trying to look taller.

I cannot show you the image 11newells posted on DeviantArt because of its size. She did an amazing job of putting me and the Princesses of Equestria (Celestia, Luna, Cadence, and Twilight Sparkle) in a meeting near Canterlot with the prehistoric newcomers: dinosaurs. Right now, the Princesses and I are meeting with Kings T-Rex and Spinosaurus. We have not seen anything so amazing in Equestria since pony encounters with dragons.

Name: Genus, Baryonyx

Time Period: Early Cretaceous Period, 125 mya

Distribution: Europe

Description: Like other spinosaurids, the 33 foot (10 meter) long Baryonyx had a long, crocodile-like snout. Each hand had 3 large claws, including one massive 13 inch (35 centimeter) long claw that was probably on the thumb. The curved tips on the claw were likely used to hook prey.

Diet: Carnivore. It is believed that Baryonyx was primarily piscivorous. The remains of fossilized fish have been found in the stomach contents of Baryonyx skeletons. The long snout and serrated teeth would’ve been well-suited for catching fish. However, dinosaur remains have also been found in Baryonyx stomachs, suggesting that this predatory dino may have been an opportunistic predator.

Fun Facts: Baryonyx was the first fish-eating dinosaur to be discovered.

“Crocodile mimic”
Early Cretaceous, 121-113 million years ago

Suchomimus was a smaller relative of Spinosaurus, though it was still 36 feet in length! It had a long, thin skull full of snaring teeth, suggesting it dined primarily on fish – a plentiful resource in its then-swampy western Africa habitat. Its name means “crocodile mimc,” because crocodiles run on two legs and roar now.


     It had been a few days since their drunken rendezvous and Lowery really wanted to see Anna again. So, on his lunch break, he ate quickly and made his way over to the spinosaurids’ paddock. After searching for a few moments, he caught sight of the woman through the glass and gave her a tight-lipped smile and a rose his hand which held a Starbucks drink intended for her.

snakeinthemanor asked:

Whats the possible evolution of Spinosaurus' sail that led to its shape? Its sail has a shape that is very different to other sailed-back animals known.

There, really, is no telling - spinosaurs had sails that were all over the place. Ichthyovenator had a notched sail, Irritator had a low but consistent sail, Suchomimus had this kind of weak half-arsed sail over its hips, Ostafrikasaurus and Baryonyx didn’t even have sails, and the others we really don’t know.

However these wonky shapes evolved, they may have been in some way more or less related to display, decked out in ornamental features or flashy colours. Perhaps in more derived spinosaurids (particularly the semi-aqutic Spinosaurus, which would have experienced some cold water at times) the sail became thermoregulatory, for either heating or cooling depending on the circumstances. At present, there really isn’t a way to tell what spinosaurids used their magnificent sails for; it is one of the great mysteries that surrounds this group.

“Fish hunter”
Early Cretaceous, 125-112 million years ago

This Asian spinosaurid grew to between 25 and 30 feet long. Its distinctive silhouette featured two separate sails, unlike the larger and single-sailed Spinosaurus. One theory is that Ichthyovenator initially had one complete sail, but thought the notch looked “hardcore” and didn’t know when to stop shaving.

snakeinthemanor asked:

How strong is Spinosaurus' skull and bite force estimated to be?

There is, in fact, surprisingly little information about this, despite the amount of press there has been surrounding the bite force of Tyrannosaurus rex. The only real reliable source of information about the bite force of Spinosaurus aegyptiacus comes from a screenshot of Kenneth Carpenter’s 2005 book, The Carnivorous Dinosaurs:


While it doesn’t contain good ol’ Spinosaurus itself, because the skull is relatively poorly known, it does contain the bite force of Suchomimus. Since the skulls of spinosaurids were generally fairly similar, think “slightly stronger than an alligator,” amounting to roughly 1.79 tons according to a quick back-of-the-envelope calculation.
