Named By: Michela M. Johnson, Mark T. Young & Stephen L. Brusatte - 2020.
Classification: Chordata, Reptilia, Thalattosuchia, Machimosauridae, Machimosaurinae.
Species: A. baroni (type).
Size: Uncertain due to lack of fossil remains.
Known locations: Madagascar - Kandreho Formation.
Time period: Bathonian of the Jurassic.
Fossil representation: Partial skull and osteoderm.
named as a species of Steneosaurus,
was found to
represent a distinct genus in a university thesis written by Michela
M. Johnson in 2019. The following year a new genus description
was published for S. baroni, and thus the
Andrianavoay genus was
established. Andrianavoay was a thalattosuchian,
but a more common
term for such a creature is a sea crocodile. Andrianavoay
spent much of its life swimming and hunting in the Jurassic oceans,
probably hunting for other aquatic creatures.
