The present study attempts to improve the original description of Favrella lorensis (Lisson, 1907) Carlos Lisson Beingolea as first time. The species was originally reported without information by international researchers. The present material was collected at the Morro Solar, Chorrillos, Lima. Seventy samples were selected from the Vera Alleman collections, deposited in the Natural History Museum “Vera Alleman Haeghebaert” in Ricardo Palma University. Favrella lorensis (Lisson, 1907) holotype T.19 (48703) is located in the Museum of Mineralogy and Paleontology of the Faculty of Geological Engineering of the National University of Engineering.  Our description was complemented adding the partial description of the suture and examples with trapezoidal section. In addition we have the first collection of Favrella lorensis (Lisson, 1907) in Peru.

The work aimed was to report ethnopaleontological studies of popular culture and to report some cases of the traditional uses of fossils in the Peruvian people in the last century and today. Eight items of sociocultural infl uence were used: artistic or aesthetic, commercial or economic, legal concept, health, psychic and spiritual utilities, playful meaning, and symbolic or identity. Preliminary results mention the use of the fossils as magical objects, a physical manifestation of the spirits of the jungle such as “Tunche” or ritual objects on the shaman tables (ammonites, sea urchins, oysters, gastropods, etc.) and log fossils “kis-huar” interpreted as “sacred tree of the Inca.” In the archaeological context it refers to the Inca, Paracas, and Nasca cultures. Th is preliminary information shows us the need to design new specifi c research projects with multidisciplinary tea...

Presentamos aportes para mejorar a las descripciones originales de Favrella lorensis (Lisson, 1907) a partir de 70 ejemplares recolectados en la localidad tipo. El material fue recolectado del Morro Solar, Chorrillos, Lima y después depositadas en el Museo de Historia Natural “Vera Alleman Haeghebaert” de la Universidad Ricardo Palma, Lima, Perú. Se comparó con el holotipo T.19 (48703) de F. lorensis, el cual  se encuentra en el Museo de Mineralogía y Paleontología de la facultad de Ingeniería Geológica de la Universidad Nacional de Ingeniería, Lima, Perú  y  se revisó bibliografía taxonómica especializada. Complementamos  la descripción con: Parte parcial de la sutura, ejemplares con sección trapezoidal, individuos de diferentes tamaños y  además de tener la primera colección de F. lorensis del Perú.

Favrella lorensis (Lisson, 1907), es una especie de ammonite incluido en el género Favrella por Douvillé en el año 1909, posteriormente otros autores han dudado de su pertenencia a este género debido a la falta y desconocimiento del material presentado por el autor original sobre esta especie. La finalidad del presente estudio es aportar al conocimiento taxonómico de Favrella lorensis (Lisson, 1907). El lugar donde se recolectó el material fue el Morro Solar, Chorrillos, Lima. Se seleccionaron 70 muestras de las colecciones Vera Alleman, depositadas en el Museo de Historia Natural “Vera Alleman Haeghebaert” de la Universidad Ricardo Palma. Con la presente tesis se han determinado 70 ejemplares de la especie Favrella lorensis (Lisson, 1907). Comparando con el holotipo y revisando bibliografía taxonómica especializada. De los cuales el 70% pertenecen al miembro La Virgen y el 3...

Propolis is a resinous substance produced by bees, and various investigations show that it has antioxidant, antimicrobial, and antifungal properties, which is why it is considered a great alternative as a natural preservative for foods and beverages, compared to artificial preservatives. The objective of this research work was to microbiologically evaluate the useful life of peach nectar with propolis as a natural preservative, under the parameters of NTS N°071-MINSA/DIGESA-V.01. The methodology used consisted of preparing nectar samples with different concentrations of propolis (0.03% and 0.05%) and storing them for two, five and nine days at room temperature, subsequently performing the seeding and microbiological count for mesophilic aerobes, coliforms total, molds and yeasts. The results showed a greater antimicrobial effect on total coliforms and molds, for nectar samples with prop...
