Description
Squalicorax falcatus
Named by L. Agassiz, 1843 (Generic name by Whitley, 1939)
Diet: Carnivore and Piscivore (Prey included ichthypdectes and other fish, the diving birds such as Hesperornis, turtles, and small marine reptiles as a tooth of Squalicorax was found embedded in the flipper of a Dolichorhynchops; it was also an opportunistic scavenger of carcasses from both the water and even from land as a Squalicorax tooth was embedded in the metatarsal foot bone of a hadrosaurid dinosaur that has already died on land and its body floats away in the Western Interior Seaway)
Type: Chondrichthyes Elasmobranchii Laminiforme (Anacoracidae) galeomorphis selachii shark
Size: 6.1 feet (1.8 meters) long and around 500 lb. (for this species)
Region: North America (Kansas, South Dakota, and Wyoming USA) for this species (Note: Teeth attributed to this species were found in Canada, France, Czech Republic, and Morocco)
Age: Late Cretaceous (100 to 72.1 million BC; Cenomanian to Campanian)
Enemies: Cretoxyrhina mantelli (ginsu shark); large mosasaurs such as Tylosaurus
Episode: Sea Monsters - The Most Dangerous Sea Ever (undescribed; its actually a re-used model of megalodon that also appeared in the series)
Info: Although sharks had their roots dating back more than 420 million years to the Silurian period (Note: fossil skin scales of sharks have been found dating back 455 million years to the Ordovician period) and have since thrived, diversified into strange shapes and sizes, becoming voracious predators, surviving dramatic events and changes as well as competition with other marine predators, but the first modern sharks known as galeomorphis within the selachii subdivision evolved around nearly 190 million years ago in the Early Jurassic period (the other line within the selachii subdivision known as the squalomorphs that lead to today's dogfish and their relatives evolved a little later in the Jurassic while around that same time period came the batoids subdivision which includes the rays, skates, and sawfish of today) and during Cretaceous times (beginning around 100 million years ago), they thrived and diversified into most groups, becoming voracious predators despite living alongside and competing with marine reptiles such as the mosasaurs . The so-called "Crow shark", Squalicorax was a medium-sized shark the prowled the Western Interior Seaway of North America (other members of the genus were found in North Africa, Europe, West Asia, and even New Zealand) with teeth surprisingly similar to those of a Tiger shark of today, a member of the lamniform (mackeral) shark order (which includes many living shark species such as the Great white), and was a coastal predator as well as an opportunistic scavenger - a Squalicorax tooth was found embedded in the foot bone of a hadrosaurid dinosaur in which the already dead floats in the surface of the Western Interior Seaway after it died on land.

Note: Based on en.wikipedia.org/wiki/Squalico…

It's too bad that the original series didn't include the so-called "Ginsu Shark" Cretoxyrhina mantelli. Why didn't they? If Walking with Dinosaurs and Sea Monsters gets rebooted and make an episode or segment that's set in the Western Interior Seaway (or Niobrarra Formation, Kansas), they should include that killer shark!
