Testing extinction events and temporal shifts in diversification and fossilization rates through the skyline Fossilized Birth‐Death (FBD) model: The example of some mid‐Permian synapsid extinctions

Cladistics, Volume 40, Issue 3, Page 282-306, June 2024.
Abstract In the last decade, the Fossilized Birth–Death (FBD) process has yielded interesting clues about the evolution of biodiversity through time. To facilitate such studies, we extend our method to compute the probability density of phylogenetic trees of extant and extinct taxa in which the only temporal information is provided by the fossil ages ...

Registro de una transgresión marina de Pensilvania - Cisural, sur de Bolivia: ¿un evento de corta duración en el oeste de Gondwana? [PDF]

, 2017
Largely terrestrial Pennsylvanian strata (Macharetí and Mandiyutí groups) in Bolivia and northern Argentina contain a brief marine incursion. Dominated by glacio-fluvial and glacial diamictites, much of the thick succession is peri-glacial in origin and ...

Palaeoenvironmental control on primary fluids characteristics of lacustrine source rocks in the Autun Permian Basin (France)

BSGF - Earth Sciences Bulletin, 2017
The Autunian (Late Gzhelian-Sakmarian, ∼295 Ma) of the Autun Basin (Saône-et-Loire, France) is well known for its lacustrine oil-shales and boghead that were exploited during the 19th and 20th centuries. A study of the kerogen geochemistry, palynofacies,

Dispersed conducting tissue fromthe Gzhelian (Saberian) of the Kounov Coal in the Kladno-Rakovník Basin, Czech Republic

Geologia Croatica
The late Pennsylvanian Kounov coal seam yielded exceptionally well-preserved vascular elements. Their determination is questionable due to their fragmentary nature. Scalariform, reticulated and pitted tracheids prevail. They are comparable with the sphenopsid plants Arthropitys and Sphenophyllum.
