Un nuevo género y especie: Pilummede penderensis (Decapoda: Brachyura) de la Formación de piedra caliza Castle Hayne (Eoceno) del condado de Pender, Carolina del Norte (EE. UU.)
Contenido principal del artículo
Resumen
El hallazgo de nuevo material de estudio en dos conocidos afloramientos de los niveles Bartoniano y Priabonianos, de la Formación Castle Hayne Limestone (Eoceno) en el Condado de Pender (Carolina del Norte, EUA), nos permite describir un nuevo género y una nueva especie, Pilummede penderensis, y al mismo tiempo asignarle especímenes previamente descritos como Lessinicarcinus euglyphos. Aunque los caparazones dorsales presentan una exquisita conservación, únicamente algunos restos de sus partes ventrales se han conservado, lo que impide su exacta asignación familiar. Sin embargo, en base a algunas similitudes, ubicamos el nuevo taxón en Pilumnoidea, con reservas. Las comparaciones con otras formas relacionadas, muestran que el patrón dorsal de Pilummede penderensis es ampliamente compartido por diversas formas de decápodos, tanto fósiles como actuales.
