Abstract

 Nine crab remains preserved in Miocene amber from Chiapas are reported. Systematic affinities of the crab remains indicate that they belong to the Sesarmidae family. Semi-terrestrial sesarmid species are frequently found in mangroves and thus their presence in Lower Miocene (Aquitanian) amber from mines of Campo La Granja, Chiapas reinforce previous interpretations of a mangrove paleoenvironment near the ancient Gulf of Mexico coast.

Keywords: Crabs, amber, Miocene, Aquitanian, Chiapas, Mexico.
