A decapod fauna from the Miocene Tuxpan Formation, eastern Mexico
Journal of Paleontology (May 1999) 73 (3): 407-413

Abstract

The first formal report of Tertiary portunid crabs for Mexico is based on two new species, Portunus atecuicitli and Necronectes tajinensis, from the middle Miocene beds of the Tuxpan Formation in Veracruz, east-central Mexico. Associated crustacean remains include fragments of calappid fingers, calappid carapace fragments possibly assignable to Matuta Fabricius, and callianassid hands. Low tolerance to osmotic variations of recent species of Portunus confirms paleoenvironmental interpretations for shallow, euryhaline, tropical waters during deposition of the Tuxpan Formation.
