Giant Mosasaur Fossil Found: Sea Dragon Discovery!

Mosasaurs were a varied team of marine reptiles. Researchers are still identifying the sizes of the biggest mosasaur types, however they likely reached a maximum size of around 50 feet (15 m). One of the largest samplings on document is a head that belonged to M. hoffmanni and is estimated to be around 56 feet (17 meters) long, according to a 2014 research study published in the journal Process of the Zoological Institute RAS.

Mississippi’s Ancient Sea Life

“Mississippi was entirely covered at the time by warm superficial exotic sea that was teaming with life, consisting of a large diversity of sharks, fish, marine lizards, and ammonites,” Starnes claimed. “Pterosaurs and also some birds would certainly have been flying overhead while a selection of both plant and meat-eating dinosaurs of various sizes and kinds would have been strolling the coast lines and via the woody woodlands along the coastal estuaries.”

Discovery of the Mosasaur Vertebra

James Starnes, a geologist at the Mississippi Department of Environmental Top quality, found the fossil protruding from a stream bed just southern of Starkville on April 15, he informed Live Science in an e-mail. His fellow geologist, Jonathan Leard, then thoroughly pulled it out of the sediment.

Researchers just located a single vertebra from the animal and aren’t certain precisely just how huge the mosasaur was in total amount, however it is estimated to have actually been at least 30 feet (9 meters) long, Hattiesburg American reported.

Mosasaur’s Place in History

In addition to being among the biggest, M. hoffmanni was also one of the last mosasaurs. The group went vanished along with non-avian dinosaurs after the Chicxulub asteroid pounded right into Planet 66 million years back. The abundant marine ecological communities that mosasaurs depended upon broken down complying with the strike, bringing the power of this leading sea predator to a permanent end.

Mosasaurs, or “sea dragons,” ruled the seas when dinosaurs dominated the land in the direction of the end of the Cretaceous period (145 million to 66 million years ago). The freshly uncovered fossil belonged to Mosasaurus hoffmanni, which was one of the largest– if not the biggest– mosasaur species.

Mosasaur’s Diet and Size

Researchers are still figuring out the dimensions of the biggest mosasaur varieties, but they likely got to a maximum size of around 50 feet (15 m). Starnes and his coworkers compared the fossil to the largest mosasaur remains held in the Mississippi Gallery of Natural Scientific research, which consist of jaws, parts of a tooth and a skull. In other words, the new fossil appeared to belong to a mosasaur that was bigger or as big as the biggest in the state gallery. Huge mosasaurs likely consumed whatever they wanted for the a lot of component, consisting of fish, sharks, sea birds and also other mosasaurs– scientists have found the remains of mosasaurs in the fossilized bellies of other mosasaurs. As being one of the largest, M. hoffmanni was additionally one of the last mosasaurs.

Fossil Comparison & Size Estimate

M. hoffmanni was a peak predator, searching down prey with big jaws and conical teeth. Huge mosasaurs most likely ate whatever they desired generally, consisting of fish, sharks, sea birds and even various other mosasaurs– scientists have located the remains of mosasaurs in the fossilized bellies of other mosasaurs. The gigantic mosasaur that left behind this particulare vertebra likely had no shortage of food in what is now Mississippi, which had a very various atmosphere towards completion of the Cretaceous.

The freshly found vertebra fossil is more than 7 inches (18 centimeters) wide at its best factor. Starnes and his coworkers compared the fossil to the largest mosasaur remains kept in the Mississippi Museum of Life Sciences, which include jaws, portions of a tooth and a skull. Starnes kept in mind that the jaws and head appeared to be from a smaller sized specific than the individual represented by the new vertebra, however the tooth looked like it came from a person that was a lot more similar in size to the brand-new specimen. In other words, the brand-new fossil appeared to belong to a mosasaur that was larger or as large as the biggest in the state museum. Starnes noted it could be the biggest in the state’s background.

“I promptly knew what it was, but was completely awe struck by its size,” Starnes claimed. “The sensation you obtain when you find a fossil, also as a professional, never ever gets old. However when you locate something you have never seen before, the elation can be frustrating.”
