In this work, it is performed a description about the methodology that is used in Mexico for the study of microfossils. This as part of the initiative of the first Workshop about the rescue of micropaleontological material carried out by the Paleobiology Laboratory of the Autonomous University of Puebla (BUAP), where was made an attempt to formaliz...
Two serpulid species, Protula? antiquata? and Propomatoceros? sp., are recorded from the Morelos Formation (mid-Cre-taceous) in Mexico. Serpulid tube structure is microcrystalline; the examined tubes are slightly diagenetically altered, but growth layers are well preserved. The short, straight growth layers with slightly curved distal ends in Protu...
Paleogeographic elements formed by the Albian and the Cenomanian carbonate sequences, from the Valles-San Luis Potosí platforms (PVSLP) and the Tuxpan platform, developed reef environments on their borders corresponding to the El Abra Formation. This formation comprises lagoon facies (El Abra member) and reefal facies (Taninul member). El Abra Form...
Ichnology is an important tool for palaeoenvironmental analysis. The first part of this chapter includes a brief review about the development of ichnology as a science, followed by some basic concepts about trace fossils and biogenic sedimentary structures, including their formation and description. Posteriorly the basis of the different proposals...
The Chicontepec Basin is located in the states of Veracruz, Hidalgo, and Puebla, in the central and eastern region of Mexico. The basin was formed during the Paleocene-Eocene, due to the orogenic process associated with the Sierra Madre Occidental (SMO) formation, and by lithospheric flexure with the consequent subsidence that allowed the developme...

Quantifying the effects of drilling predation on juvenile and adult gastropods is important for understanding the paleoecology of communities. Although numerous studies have examined predation on adult shells, virtually no reports cover juvenile specimens. We compare predation frequency and prey effectiveness between juvenile and adult gastropods i...
Total concentrations of Ba, Cd, Co, Cr, Cu, Mn, Ni, Pb, V, Zn, and As together with Sr and Pb isotopic compositions of seabed sediments from the worldwide famous tourist destination of Acapulco Bay, Guerrero (southern Mexico) were determined to reveal the origin of detritus and toxic elements (TEs), their potential natural and anthropogenic sources...
We report on an early Pliocene marine gastropod assemblage from Guerrero State, Mexico. Sixty-three gastropod species were identified and used to interpret their paleogeographic significance. From this assemblage, 15 species are reported as fossils for the first time, and 10 have not been previously reported older than early Pleistocene. The genus...
Introduction:
The taphonomic attributes of a faunal assemblage provide information about which agents affect the distribution and preservation of ancient or newly formed biogenic materials during depositional and post-depositional processes. Actuotaphonomy thus is a valuable tool for reconstructing fossil communities because it establishes analogie...
RESUMEN Los recursos forestales son importantes para el desarrollo de un territorio, no sólo por la extensión que estos representan, también lo son por los beneficios ecológicos, económicos y sociales (PNUMA, 2014). En este sentido, el objetivo de la presente investigación fue identificar las áreas aptas para aplicar el programa de reforestación Pr...
La Universidad Nacional Autónoma de México a través de sus escuelas y facultades, entre ellas, la Facultad de Ingeniería, ha promovido la divulgación de apuntes, prácticas, libros de texto y otras publicaciones con la finalidad de complementar las cátedras que se imparten en los diferentes planes de estudio de las carreras de Ciencias de la Tierra...
In this study investigates the predatory activity on a Holocene gastropod from the Argentinean Malacological Province. Buccinanops deformis (King, 1832), endemic in the southern hemisphere, is a typical taxon of cold-waters and high latitudes. We observed direct evidence of durophagy as lethal and sublethal damage. Sublethal damage was studied usin...
This study presents both qualitative and quantitative data regarding marine mollusk (gastropods and bivalves) shell bioerosion and encrustation based on death assemblages obtained from a recent supratidal environment in Playa Norte, Veracruz State. The objectives of this study were to assess the nature of bioerosion and encrustation processes and t...
Taphonomic processes in a Pennsylvanian regional encrinite (Atokano), Sonora, Mexico. Crinoids have an extensive fossil record and were a major component in Paleozoic marine communities; encrinites are common crinoid accumulations where specimens are totally disarticulated from the Ordovician to the Jurassic. In Sonora, Mexico, the crinoid skeleton...
En esta versión digital de la segunda edición del libro Manual para el Trabajo Geológico de Campo se presentan los procedimientos más comunes en el trabajo de campo; desde recomendaciones en el uso del equipo básico de campo como la brújula y el martillo de geólogo, hasta rutinas y formatos para obtener y registrar datos geológicos. Con el uso del...
Predation as an evolutionary mechanism of diversification is a topic of great interest. Durophagy is the feeding behavior of preying on hard-shelled or exoskeleton-bearing organisms. On this matter, because of their worldwide distribution, abundance, wide range of habitats, and a remarkable preservation frequency, mollusks are of particular interes...
En el Estado de Sonora existen varias localidades con rocas sedimentarias del Misisípico. Particularmente, en el área de El Bísani que se localiza en la región de Caborca al noroeste del Estado de Sonora, afloran rocas de la formaciones Represo y Venada, cuya edad misisípica (Osageano inferior), se dató, inicialmente, por la presencia del coral col...
Although the origin of life cannot be dated with precision, life must have appeared soon after the cooling of the Earth, when the existence of liquid water on the planet enabled primitive oceans to exist. In fact, fossil records support the evidence of life on Earth earlier than 3400 Ma ago. In order to understand the origin of life, it is useful t...
Los gasterópodos son un componente importante en la mayoría de los registros fósiles, sin embargo, las investigaciones se han centrado principalmente en la caracterización de las tafofacies y firmas tafonómicas en ambientes particulares. Se presentan los datos tafonómicos cualitativos y cuantitativos para el ensamblaje del gasterópodo cf. Donaldina...
Gastropods are an important component in most of the fossil record; however, investigations have focused mainly on the characterization of the tafofacies and signatures in determined environments. We present qualitative and quantitative taphonomic data for the gastropod cf. Donaldina robusta assemblages from the La Joya Formation of the Sierra Agua...
The fossil crinoids and associated fauna from the Carboniferous (Mississippian–Pennsylvanian) of Mexico (Sonora, Tamaulipas, Hidalgo, Puebla, Guerrero, Oaxaca and Chiapas States) are described. Data are based on a combination of field and published sources, including seven previously studied localities from the central and southern areas, and four...
Se muestra a la tafonomía como una rama del conocimiento paleontológico que estudia los efectos del proceso post-mortem y cómo éstos afectan la información del registro fósil.
Pennsylvanian carbonates are widespread in Sonora (Mexico) and contain a diverse biota of foraminifers and calcareous algae. Detailed studies here are devoted to the outcrops of the Sierra Agua Verde and Cerro El Tule. The Late Atokan (early Late Moscovian part), Desmoinesian (=late Late Moscovian) and Missourian (=Kasimovian) stages are especially...
The La Joya Formation of the Sierra Agua Verde, Sonora (NW Mexico) is late Atokan in age, equivalent to the early late Moscovian (Podolskian) and fusulinid biozone A3. In this alternance of cherty limestones and thin shaly beds, fusulinellid or anchicodiacean ('phylloid algae') wackestones-packstones and crinoidal rudstones-gramstones are the predo...
In the Sierra Agua Verde, central Sonora state, NW Mexico, the La Joya Formation exhibits an alternation (100 m thick) of calcareous siltstone and fossiliferous limestone with nodular cherts. This latter contains an abundant and diverse late Atokan (i.e. Podolskian =early late Moscovian, Middle Pennsylvanian) fossil assemblage composed of phylloid...
Detailed and extensive studies of Cretaceous (Aptian-Cenomanian) gastropods from 19 localities in Mexico (Baja California, Sonora, Jalisco, Colima, Michoacán, Querétaro, Puebla, Guerrero, and Oaxaca) yielded gastropod species that also have been reported from other regions in the world and, thus, support a paleobiogeographic relation with similar f...

Hello, these samples comes from Olinalá Formation (Permian age), Guerrero State, México. I need help to know if they correspond to Roadoceras, Stacheoceras and Waagonoceras (that have been reported for the locality), but this locality has a lot of ammonites, so I am not sure.
Tnks in advance
