Feather of the Penguin Penguins are highly adapted for their cold, aquatic environment. Changes in wings and feathers have allowed rapid swimming protection from near-freezing water. Clarke et al. (p. 954 , published online 30 September; see cover) describe an early penguin, dating to about 35 million years ago, that includes well-preserved feathers. The melanosomes feathers, which influence strength, as well color, like those many other birds unlike present-day penguins, even though...

Amazonia contains one of the world's richest biotas, but origins this diversity remain obscure. Onset Amazon River drainage at approximately 10.5 Ma represented a major shift in Neotropical ecosystems, and proto-Amazonian biotas just prior to pivotal episode are integral understanding Amazonian biodiversity, yet vertebrate fossil evidence is extraordinarily rare. Two new species-rich bonebeds from late Middle Miocene deposits northeastern Peru document same hyperdiverse assemblage seven...
Abstract Over 100 GPS sites measured in 2008–2013 Peru provide new insights into the present‐day crustal deformation of 2200 km long Peruvian margin. This margin is squeezed between eastward subduction oceanic Nazca Plate at South America trench axis and westward continental American beneath Eastern Cordillera Subandean orogenic wedge. Continental active faults data reveal rigid motion a Forearc Sliver that extends from to Western‐Eastern Cordilleras boundary moves southeastward 4–5 mm/yr...

In northern Peru, a 500 km long regional balanced section has been constructed across the eastern Andean wedge, using fieldwork, industrial seismic sections, and wells. The structure is characterized by thin-skinned thrust system involving Eastern Cordillera (EC), sub-Andean zone (SAZ), Marañón foredeep.

Abstract The Middle Miocene has been identified as a time of great diversification in modern lineages now distributed tropical South America, and when basic archetypal traits defining Amazonia appear, including climatic humid conditions, floral physiognomy phylogenetic composition rainforests. Nonetheless, localities America are poorly known, especially at low latitudes where only one species‐rich locality, La Venta Colombia, extensively studied. present contribution describes the mammal...
Gavialoid crocodylians are the archetypal longirostrine archosaurs and, as such, understanding their patterns of evolution is fundamental to recognizing cranial rearrangements and reconstructing adaptive pathways associated with elongation rostrum (longirostry).

Yet phylogenetic relationships evolutionary ecology spanning ~70 million-years crocodylian...

Abstract The Oriente Basin is part of the retro-arc foreland basin system that developed in zone transition between Central Andes and Northern since Late Cretaceous times. It deformed by thick-skinned tectonics related to inversion pre-Cretaceous extensional fault systems, which have broken into three tectonic domains during mean periods (Late Cretaceous–Palaeocene, Early Eocene Miocene). northern present-day Sub-Andean wedge-top corresponded, Cretaceous, forebulge depozone.

Abstract Sediment-hosted gold deposits represent a significant portion of the world’s resources. They are characterized by ubiquitous presence organic carbon (Corg; or its metamorphosed product, graphite) and systematic occurrence invisible gold-bearing arsenian pyrite. Yet role played these features on ore formation distribution remains long-standing debate. Here, we attempt to clarify this question via an integrated structural, mineralogical, geochemical, modeling study Shahuindo deposit...
Deep learning approaches for geological subsurface reconstruction typically require extensive training datasets, limiting their practical application in geosciences where data acquisition is costly and sparse. We present a methodology using sparse convolutional autoencoders that effectively learns from synthetically generated while maintaining strong generalization to real-world scenarios. Our model trained exclusively on synthetic basin boundary configurations corresponding forward-modeled...
Formation of the Bolivian eastern cordillera started at end Oligocene and continues to present day with thrusting affecting Sub Andean Zone since late Miocene. The 'classical' source rock is Devonian, but Silurian interval has some potential. Their initial original potential not high they are thick (700 m, Los Monos Fm) may be thicker still due stacking in thrust duplexes. three phases sedimentation during Tertiary each start conglomeratic deposits discordant over previous one.
