Article
We describe fossil liverworts, mosses, and thallose forms of unknown affinity from the Barreal and Cortaderita formations (Sorocayense Group, Middle Triassic) in the Barreal depocenter, southwestern San Juan Province. The specimens are impressions-compressions of gametophytes and sporophytes, preserved in claystones, siltstones, and tuffaceous and...

La gran mayoría de la divulgación científica en paleontología trata sobre los dinosaurios. Es por ello que mucha gente cree que la paleontología es el estudio de dicho grupo de animales. Este compendio de textos surge de la necesidad de contarle a la comunidad que la paleontología es mucho más que dinosaurios. Este libro es un compendio de veintidó...

Piper hieronymi es un arbusto o pequeño árbol que habita las selvas de Jujuy, Salta, Tucumán y Misiones, en Argentina. Sus tallos y ramas tienen nudos muy engrosados, y anatómicamente exhiben un arreglo policíclico de los haces vasculares. Este trabajo tiene como objetivo caracterizar la organización vascular y el leño en tallos secundarios de P. h...

The end-Permian crisis was the most severe extinction event in the Phanerozoic. In Southwestern Gondwana, this crisis was related to the development of the Choiyoi Silicic Large Igneous Province. In the Southern Hemisphere, the Glossopteridales were dominant in the Permian, and they declined at the Permian-Triassic boundary and were replaced by the...

A systematic description of Heidiphyllum leaves, ovulate structures of Dordrechtites and undetermined conifer wood is provided. This is the first description of these elements for the Ischichuca Formation, and the first...

A comienzos del Paleozoico todos los seres vivos eran acuáticos. En el Ordovícico, el segundo período de esta Era, las plantas se aventuraron fuera del agua. Las pioneras estaban represent...

A new species of Osmundopsis Harris is described based on several impression-compression fossils from the upper section of the Potrerillos Formation (Uspallata Group) at Cerro Cacheuta Hill, Mendoza Province, Argentina. Osmundopsis zunigai sp. nov. is characterized by having fertile pinnae with a slender striate rachis, bearing widely separate, opp...

El registro de licófitas del Mesozoico argentino es escaso, por lo que el hallazgo de nuevos ejemplares es de gran importancia en el conocimiento de la biodiversidad fósil. En esta contribución se describen tallos de licófitas herbáceas provenientes de la Formación Barreal (Anisiano, Triásico Medio, provincia de San Juan) y de la Formación Potreril...

The record of Mesozoic lycophytes from Argentina is scarce, for this reason the finding of new samples is significant for the knowledge of the fossil biodiversity. In this contribution, stems of herbaceous lycophytes coming from Barreal Formation (Anisian, Middle Triassic, San Juan Province) and Potrerillos Formation (Carnian, Upper Triassic, Mendo...

Serjania laruotteana Cambess. (Sapindaceae) is a liana that inhabits the forests of Brazil, Paraguay and Argentina (Misiones and Corrientes provinces). As many lianas of the family, it presents a compound vascular system in their stems. This type of stem pattern has been subject to several interpretations, both in descriptive terms and in developme...
