The first publicized discovery of a partial fossil mosasaur skull in 1764 by quarry-workers in a subterranean gallery of a limestone quarry near the Dutch city of Maastricht, preceded any major dinosaur fossil discoveries but remained little known. Michael S.Y. Mosasaurs (from Latin 'Mosa' meaning the 'Meuse river' in the Netherlands, and Greek sauros meaning 'lizard') are an extinct group of serpentine marine reptiles that thrived worldwide in the earth's oceans during the Cretaceous Period. Many of the 'dinosaur' remains found on New Zealand are actually mosasaurs and plesiosaurs, another group of Mesozoic predatory marine reptiles.

"That was a Wednesday night I got the phone call," he added. [5] This debate was furthered when French scholar Faujas de Saint-Fond argued that the remains belonged to a crocodile. "They shut down what they were doing in that area, [and] moved to another part of the mine," Spivak added.

On November 16, 2005, research reported in Netherlands Journal of Geosciences confirmed that the recently uncovered Dallasaurus turneri is an early link between land-based monitor lizards (such as the Komodo dragon) and the aquatic mosasaurs.[6]. "That was a Wednesday night I got the phone call," he added. By the early Coniacian, there were three major genera (Tylosaurus, Platecarpus and Clidastes) of mosasaurs that had evolved.

The first fossilized remains were discovered in a limestone quarry at Maastricht on the Meuse in 1778, and the first genus of mosasaur, Mosasaurus, was named.

"Enter the Mosasaurs," Chapter 9 in "Oceans of Kansas: A Natural History of the Western Interior Sea." It was the mosasaur, which dominated the seas 70 million years ago, when most of the planet was ocean, said Royal Tyrrell Museum of Palaeontology's director of resource management Dan Spivak, on the Calgary Eyeopener Monday. Based on features such as the loosely-hinged jaw, modified/reduced limbs and probable locomotion, many researchers believe that snakes share a common marine ancestry with mosasaurs, a suggestion advanced in 1869, by Edward Drinker Cope, who coined the term "Pythonomorpha" to unite them. comm. Comments are welcome while open. The mosasaur wasn't actually a dinosaur — it was more of a sea monster — and it lived in Bearspaw Sea. Halisaurus arambourgi, a mosasaur from the Late Cretaceous of Morocco. "Friday, we had a team down on site to assess what was there and then the following Monday we had a full team of I believe four people going down with all the appropriate equipment to excavate this thing in the sand for about four days, five days. While it is not possible at this point to determine whether this feeding activity was the result of an attack on a live mosasaur or the scavenging of a carcass, it is probable that a five or six meter Ginsu would behave much like a modern Great White shark, or an extinct Carcharocles megalodon. ", Stephen Hunt is a digital writer at the CBC in Calgary. That's when Spivak got the call at the museum. Several sets of mosasaur remains, that had been discovered earlier at Maastricht but were not identified as mosasaurs until the nineteenth century, have been on display in the Teylers Museum, Haarlem, procured from 1790. Those rainbow shells are being incorporated into jewelry. 2003), reported that the first mosasaur skull, somewhat less complete than the type specimen of Mosasaurus hoffmanni (Mantell 1829), was actually discovered in 1766, near St. Pietersburg, Maastricht and is still on exhibit in the the Teylers Museum, in Haarlem (No. "It kind of looks a little bit like a swimming Komodo dragon, maybe with a bit pointier nose.". Those rainbow shells are being incorporated into jewlery and other things. Comments on this story are moderated according to our Submission Guidelines. Any specimens that are recomposited will be mentioned in the descriptions. Plesiosaurs were also less numerous in the Late Cretaceous than during the Jurassic, and had evolved into some very specialized forms like the long-necked elasmosaurs. The Royal Tyrrell Museum staff handling the mosasur fossil find guessed that it was between 6and seven metres long.

The mosasaur wasn't actually a dinosaur — it was more of a sea monster — and it lived in Bearspaw Sea. Mosasaur bones have also been found with shark teeth embedded in them.

The first documented specimen of a mosasaur fossil was in the town of Maastricht, Netherlands in 1764, in which a partial skull was discovered by limestone quarry-workers along the Meuse River. Ammonite shells have been found with what appear to be mosasaur bite marks, but there is some question as to whether or not these holes were caused by mosasaur bites or far more likely, by the attachment of limpets. Picture a Komodo dragon seven metres long surging through the ocean to gobble up fish, turtles — pretty much everything in sight. Larger mosasaurs were more typical: mosasaurs ranged in size up to 17 m. Hainosaurus holds the record for longest mosasaur, at 17.5 meters.
