Siamodon
Name: Siamodon
(Siam tooth).
Phonetic: Sie-am-o-don.
Named By: Eric Buffetaut & Varavudh
Suteethorn - 2011.
Classification: Chordata, Reptilia, Dinosauria,
Ornithischia, Ornithopoda, Iguanodontia.
Species: S. nimngami (type).
Diet: Herbivore.
Size: Unknown due to lack of remains.
Known locations: Thailand, Nakhon Ratchasima
Province - Khok Kruat Formation.
Time period: Aptian of the Cretaceous.
Fossil representation: Left maxilla (one of the
tooth bearing bones of the upper jaw), and tooth.
Although
named from only a maxilla and tooth, the remains of this dinosaur are
still complete enough to confidently identify it as an iguanodont. In
life Siamodon would have been a medium to large
sized ornithopod
dinosaur that would have been primarily quadrupedal, but also
occasionally bipedal. Although identified as being separate,
Siamodon is considered to have been similar to
Probactrosaurus,
also
known from Asia.
Siamodon
should not be confused with the similarly named spinosaurid tooth taxon
Siamosaurus
which is also from Thailand, although this would come as
no surprise to those of you that already know that Siam is the ancient
name for Thailand.
