This a list of Mosasaur species that are some of the smallest of their kind. Having more smaller species represented in the lagoons would make them more interesting. I was thinking it would be great to add one to the game.

It sounds like a good idea, but they would have to be smaller in size than the ones we currently have in the game. According to Wikipedia, Mosasaurus is estimated to have grown between 7 meters (23 feet) and 18 meters (59 feet). Tylosaurus is estimated to have grown 5 meters (16 feet) and 15.8 meters (52 feet). In both cases, it appears the developers used the larger size estimates when choosing how to design them. Some other species that might work include:
Vallecillosaurus, An extinct genus of mosasauroid from the Late Cretaceous period, that lived in Mexico, in the state of Nuevo León. It was a relatively small reptile measuring less than 1 m (3.3 ft.) long.
Komensaurus, A genus of basal aigialosaurid mosasauroid from the Late Cretaceous period. It was found at Komen in Slovenia. It was a relatively small reptile, reaching 1 m (3.3 ft) in length and 2 kg (4.4 lb) in body mass.
Portunatasaurus, An genus of mosasauroid squamate that lived during the Late Cretaceous period found in the Adriatic-Dinaric Carbonate Platform in present day Croatia. It was a relatively small reptile, reaching 1 m (3.3 ft) in length and 2 kg (4.4 lb) in body mass. It is believed to have lived in a lagoon ecosystem. It showed adaptation to a semi-aquatic lifestyle.
Tethysaurus, An extinct genus of tethysaurine mosasauroid from the late Cretaceous period. It grew to be around 3 m (9.8 ft) long and weighed 70 kg (150 lb). The name means "Tethys' lizard of Nopcsa", a reference to the Greek goddess of the sea Tethys and also the name of the Tethys Ocean, an ancient sea between southern Europe and northern Africa.
Sarabosaurus, a monospecific genus of plioplatecarpine mosasaurid from the lower Turonian Tropic Shale of Utah, United States. The genus name is derived from the Arabic word "sarab", meaning desert mirage and the Greek "sauros", meaning lizard. The species name was named in honor of Steve Dahl, a volunteer at the Grand Staircase-Escalante National Monument in Kanab, Utah.
Selmasaurus, An extinct genus of marine lizard belonging to the mosasaur family. It is classified as part of the Plioplatecarpinae subfamily alongside genera like Angolasaurus and Platecarpus. Two species are known, S. russelli and S. johnsoni; both are exclusively known from Santonian deposits in the United States. It grew to be approximately 3–5 meters in length. It possesses a relatively low number of teeth for a mosasaur, the lowest of any known species at the time of its discovery. Selmasaurus is unique among the mosasaurs in that its skull is unusually akinetic, meaning that it is incapable of widening to swallow larger prey. Most mosasaurs have skulls which possess "coupled kinesis" (mesokinesis and streptostyly), that is, parts of the jaw can open widely to accommodate large prey.
Kourisodon, A species of mosasaur from late Cretaceous period Vancouver Island in British Columbia, Canada and the Izumi Group of Japan. It was a small mosasaur, with an estimated length of about 3.75 meters (around 12.3 feet). Kourisodon was originally described as a member of the Leiodontini, more recently as a Clidastine.
Angolasaurus, an extinct genus of mosasaur. Definite remains from this genus have been recovered from Angola, and possibly the United States, Brazil, and Niger. It grew to be about 4 meters (13 feet) in length and weighed 200 kg (440 lb.). Its wide geographic range make it the one of the only Turonian mosasaurs with a transatlantic range.
Haasiasaurus, An extinct genus of early mosasaur, originally named "Haasia" by M. J. Polcyn et al., in honour of the palaeontologist Georg Haas. (The original name was a junior homonym of Haasia Bollman, 1893, a genus of millipedes.) Haasiasaurus was one of the oldest cenomanian mosasaur measuring 1 metre (3.3 ft) long. It was found in the Cenomanian 100 million years ago (late Cretaceous period) rocks near Ein Yabrud, in the Palestinian West Bank, approximately 20 kilometres (12 mi) north of Jerusalem.
Clidastes, An extinct genus of marine lizard belonging to the mosasaur family. It is classified as part of the Mosasaurinae subfamily, alongside genera like Mosasaurus and Prognathodon. Clidastes is known from deposits in the United States. Clidastes means "locked vertebrae", which originates from the Greek noun κλειδί, or kleid meaning key (akin to Latin claudere meaning to shut). This refers to how the vertebral processes allow the proximal heads of the vertebrae to interlock for stability and strength during swimming. It was one of the earliest hydropedal mosasaurs, representing one of the first properly marine predatory forms alongside other early hydropedal genera like Tylosaurus and Platecarpus. Clidastes was the one of the smallest of the mosasaurs, averaging 2–4 meters (6.6–13.1 ft) in length, with the largest specimens reaching 6.2 meters (20 feet) long. It is thought to have preyed upon cephalopods, fish and other small vertebrates in shallow water. Isotopic analysis on teeth specimens has suggested that this genus and Platecarpus may have entered freshwater occasionally.
