       Halisaurus Mosasaur was first named all the way back in 1869 during a period in American paleontological history today known as the ‘bone wars’. However a year later Othniel Charles Marsh, the person who named Halisaurus, became aware of a genus of fish called Halosaurus and mistakenly came to the conclusion that Halisaurus was preoccupied, and so created the name Baptosaurus to replace it. However although very similar to Halisaurus, Halosaurus is still different enough not to cause a conflict, so Halisaurus was later resurrected as a valid name, while Baptosaurus is now a synonym to it.

       With individuals ranging between three and four meters in length, Halisaurus was towards the smaller end of the size scale for mosasaurs. Rather than being apex predators themselves, Halisaurus would have been mid-range predators that hunted more for fish and squid in open water. With a global distribution stretching from Peru to North America, Across to Africa and Northern Europe, as well as a

Please be aware of the nature of fossils:

Being buried under the ground for millions of years under tons of pressure tends to be rough. No fossil comes out of the ground whole and perfect. Most fossils have undergone some restoration, while others are altered by man simply to enhance their presentation in different ways. The workers in Morocco do a very professional job, unearthing and preserving these natural treasures, however, commonly natural cracks are visible on the surface. These are part of the natural beauty of the fossil and not considered defects.
