Pronunciation: Hy-dro-ther-roe-sore-us Meaning of name: "Water beast lizard". Species: H. alexandrae Size: Estimated to have measured between 7 and 13 metres long and weighing around 2 metric tonnes. Family: Elasmosauridae. Diet: Piscivore First fossils found: Known only from a single, almost-complete skeleton discovered in the Moreno Formation of California in 1943. Named in the same year by American palaeontologist, Samuel Paul Welles. Lived: 72.1 to 66 million years ago during the Maastrichtian stage of the Late Cretaceous in the warm waters of the Western Interior Seaway which once stretched from the Arctic ocean and through the middle of what is now Canada and the United States to the Gulf of Mexico. May also have lived in the Pacific ocean.
Pronunciation: No-rip-teh-rus Meaning of name: "Lake wing". Species: N. complicidens Wingspan: Estimated to have measured around 4 metres. Family: Dsungaripteridae. Diet: Shellfish. First fossils found: Known from many specimens, including an almost-complete skeleton, discovered in the Lianmuqin Formation of western China and the Tsagan Tsab Formation of western Mongolia. Named by Chinese palaeontologist, Yang Zhongjian, in 1973. Lived: 140 million years ago during the Berriasian stage of the Early Cretaceous in what is now western China and western Mongolia.
Pronunciation: Teh-thee-sore-us Meaning of name: "Tethys lizard", after the Greek goddess of the sea. Species: T. nopscai Size: 3 metres long. Weight uncertain. Family: Russellosaurinae (a sub-family of Mosasauridae). Diet: Carnivore. First fossils found: Known only from a single, almost-complete skeleton discovered in Errachidia Province, Morocco, North Africa (date of discovery uncertain). Named by Nathalie Bardet, Xabier Pereda Suberbiola and Nour-Eddine Jalil in 2003. Lived: 93.9 to 89.8 million years ago during the Turonian stage of the Late Cretaceous in the warm oceans that once covered what is now Morocco, North Africa.

Pronunciation: As-tro-foe-caw-de-ah Meaning of name: "Star tail". Species: A. slaughteri Size: Uncertain due to a lack of fossils. Family: Uncertain Diet: Herbivore. Likely fed on both high and low-growing vegetation. First fossils found: Known only from a single, partial skeleton discovered by Maria A. Marques-Bilelo in the upper middle unit of the Paluxy Formation of Texas in 1969. Named by Michael D. D’Emic in 2012. Lived: 113 to 100.5 million years ago during the Albian stage of the Early Cretaceous in what is now the south central region of the United States.
Pronunciation: Crass-pe-do-don Meaning of name: "Edge tooth". Species: C. lonzeensis Size: Unknown due to a lack of fossils. Family: Uncertain. Possible Neoceratopsian. Diet: Herbivore. First fossils found: Known only from a handful of teeth discovered in the Glauconie de Lonzée Formation of Belgium in 1883. Named in the same year by Belgian palaeontologist, Louis Antoine Marie Joseph Dollo. Craspedodon was originally thought to be an Iguanodontid, however, a re-study done in 2007 has suggested it was actually a Neoceratopsian. If this is correct, Craspedodon would be the first Neoceratopsian discovered in Europe. Lived: 85 million years ago during the Santonian stage of the Late Cretaceous in what is now Belgium.
How can you name a dinosaur on the strength of a couple of teeth?
Because the archaeologists need something to do? 😉
When they only find a tooth or a couple of small bones, I don’t see how they can possibly know the size, colour or diet, but thereagain I’m not an archaeologist. 😳
