“…La diversidad de la cantera incluye microfósiles como foraminíferos y calciesferas, amonitas, crustáceos y crinoideos, tiburones y rayas y al menos 22 especies diferentes de peces óseos, un celacanto, además de dos reptiles, entre ellos una tortuga (González-Rodríguez et al, 2013;Schultze y González-Rodríguez, 2016;Arratia et al, 2018), por lo que es considerado como un Fossil Lagerstätte (venero fosilífero) de concentración (Bravo-Cuevas et al, 2012).…”

La Cantera Muhi es un sitio fosilífero en el noroeste del estado de Hidalgo, con una edad aproximada de 102 millones de años. La localidad está conformada por rocas calizas laminadas que se formaron en un mar somero durante el Cretácico. La cantera es explotada por miembros de la comunidad de San Pedro, para obtener lajas que son utilizadas en la construcción. Durante la extracción de las rocas, a veces encuentran fósiles marinos. Desde 1998, los miembros de la familia Yáñez han donado el material fósil que hallan, el cual está depositado en el Museo de Paleontología de la Universidad Autónoma del Estado de Hidalgo. Los fósiles recuperados en la localidad forman parte del patrimonio nacional, por eso debemos preservarlos.

“…According to the lithology and the fossiliferous content, the paleoenvironment corresponds to an open marine platform basin with well-oxygenated water, which occasionally received the alternation of distal platform neritic waters and medium neritic water (González-Rodríguez and Bravo-Cuevas, 2005;Bravo-Cuevas et al, 2009. The alternated influx of neritic water and open oceanic water in addition to the sporadic influx of coastal water, produced by fluctuations of oxygen and salinity at the site of deposit and the consequent death and preservation of the fauna (Bravo-Cuevas et al, 2012).…”

First Mesozoic Thylacocephalans (Arthropoda, ?Crustacea; Cretaceous) in the Western Hemisphere: New Discoveries from the Muhi Quarry Lagerstätte

2014

The first Mesozoic thylacocephalans from the western hemisphere are documented from the Muhi Quarry plattenkalk in the La Negra facies of the El Doctor Formation (Albian–Cenomanian), Zimapán Area, northwestern Hidalgo, central Mexico. They all are found in a single horizon at the base of the type section. These specimens represent two new genera and species, and a third undetermined species which likely also represents a new genus and species. Victoriacaris muhiensis is a shorted-bodied thylacocephalan with concave anterior and posterior notches as well as a beveled anterior spine. Polzia eldoctorensis is trapezoidal in outline with a rounded posteroventral corner. The third undetermined species is known only from one broken specimen, but has distinctive marginal spines that are not possessed by any other post-Cambrian thylacocephalan. The occurrence of such a diverse fauna of thylacocephalans markedly increases the diversity and geographic range of Cretaceous thylacocephalans, but does not offer any insights into the tempo of thylacocephalan extinction at the end of the Cretaceous.
