Tertiary freshwater Decapoda (Crustacea: Parastacidae) from the Nirihuau Basin, Patagonia, Argentina

Very well preserved specimens of a macruran decapod from the Lower (Lacustrine) Member of the Nirihuau Formation, northwestern Patagonia, Argentina, permitted description of Lammuastacus longirostris, a new genus and species of Parastacidae. The sedimentological and paleontological evidences provide...

This is the first certain record of a fossil Parastacidae from Tertiary deposits, most probably Oligocene. The fossil material shows similarities with Geocharax, the extant Australian genus considered to retain many primitive characters, and other related genera from New Zealand and Chile. -Author JOUR info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by/2.5/ar http://hdl.handle.net/20.500.12110/paper_00223360_v66_n5_p817_AguirreUrreta
