I'm back with a new book. This time I'm going to show you the many amazing, frightening and sometimes downright strange species that were lost to time.
There are so many creatures that once roamed planet Earth, our own little oasis in the vast expan...
Morning rises over the continent of North America, revealing the sea which cuts the landmass in two.
As the sun's warming rays push back the darkness, many creatures are starting their day. While the land animals are just beginning to wake up, the monsters of the sea are already wide awake.
Suddenly, the water's surface is broken by an enormous body, the head alone being 1.8 meters long. This is Leviathan, a fully grown Tylosaurus proriger.

Measuring a whopping 14.6 meters long, Leviathan is big even for a Tylosaurus, and one of the largest inhabitants in the Western Interior Seaway; however, he's still not the largest individual of his species. Most Tylosaurus prorigers grow up to be between 13 and 14 meters long, yet some individuals are able to get as long as 15 meters or more.
Leviathan takes a deep breath of fresh morning air before diving into the depths of the sea. At the moment, Leviathan is conserving his energy for the long trip ahead of him. He may not be going very quickly right now, but when he needs to move, his powerful tail can propel him at 4 kilometers per hour. This may not be very fast, but it's enough to get the job done. While his tail pushes him through the water, Leviathan's flippers allow him to steer.
Both Leviathan and other Tylosauruses are surprisingly light for their size. This insures that their mass doesn't cause them to sink. Small paddles and bones filled with fat cells add to the species' buoyancy.
As Leviathan dives deeper into the sea, his massive body effortlessly pushes him through oceanic currents.
Thanks to his gigantic body, Leviathan cannot only feed on any kind of animal he wants, but the only creature he has to worry about is another Tylosaurus. However, being this big comes with one major drawback as Leviathan must take every opportunity he gets to eat.
As he continues to swim through his territory, something catches his eye. A huge Parapuzosia bradyi is drifting through the water, and it hasn't seen him.
