A 100‐Million‐Year Gap in the Knowledge of the Evolutionary History of Bromeliaceae: A Brief Review of Fossil Records

Feddes Repertorium, Volume 132, Issue 1, Page 20-27, March 2021., 2021
Bromeliaceae arose in the Early Cretaceous, diverging from Typhaceae at ca. 125 Ma. After an apparent evolutionary stasis of 100 million years, they have undergone a high diversification starting in the Miocene. By adding fossils to the phylogenies, one can infer dates of arising and the divergence of lineages and link them to geological and climatic ...

Comparing surface digitization techniques in palaeontology using visual perceptual metrics and distance computations between 3D meshes

Palaeontology, Volume 64, Issue 2, Page 179-202, March 2021., 2021
Abstract The use of surface digitization techniques and methods in palaeontology has increased in the last two decades, mainly due to recent improvements in devices and software. However, many digitization efforts are published only as 3D models, with only a few details on the exact protocols used and sometimes not even indicating how to access these ...

Stratigraphic Relations of the Ipubi Formation: Siliciclastic-Evaporitic Succession of the Araripe Basin [PDF]

Anais da Academia Brasileira de Ciências, 2018
The Ipubi Formation represents the Aptian-Albian siliciclastic-evaporitic succession of Araripe Basin, NE Brazil. This succession comprises siliciclastic rocks (bituminous shales and claystones) and evaporites (gypsum and secondary anhydrite) and represents part of the lacustrine-shallow marine post-rift phase I.
