#sinopliosaurus

[mesozoicmarket]

A dinosaur tooth of the spinosaurid tooth taxon, cf. Siamosaurus sp. from the Grès supérieurs Formation in the Savannakhet Province of Laos. The 22-23 ridges suggest Siamosaurus, but could still be Ichthyovenator laosensis. In comparison, Ichthyovenator is described as having a total ridge count between 42 to 64. It should be noted that this is not referring to the original Siamosaurus suteethorni from the Sao Khua Formation, but a similar morphology referred to Siamosaurus sp. from the younger Khok Kruat Formation.

Name: "Sinopliosaurus fusuiensis"

Name Meaning: More Chinese Lizard 

First Described: 1975 

Described By: Hou, Yeh & Zhao 

Classification: Dinosauria, Saurischia, Theropoda, Neotheropoda, Averostra, Tetanurae, Orionides, Megalosauroidea, Megalosauria, Spinosauridae 

Sinopliosaurus is interesting in that it actually is a plesiosaur genus from the Early Cretaceous of southern China. However this particular species is known from a tooth, which was found to be similar to the tooth of Siamosaurus, indicating that it isn't actually a plesiosaur. However it hasn't been officially named yet, so it's still being called Sinopliosaurus.

A dinosaur tooth of the spinosaurid tooth taxon, Siamosaurus suteethorni from the Sao Khua Formation in Khon Kaen Province, Thailand. Unfortunately, this tooth has seen better days with much of the enamel worn away with a few repairs. Similar morphologies have been found in Laos, China, and Japan. These spinosaurine teeth have occasionally been mistaken for plesiosaurs, namely the pliosaur Sinopliosaurus.
