ABSTRACT Enantiornithes is a diverse clade of Mesozoic birds first recognized from the Upper Cretaceous sediments of a South American locality in northern Argentina. Extensive discoveries of Mesozoic birds have since been made globally, and three other South American localities have subsequently produced enantiornithine material. Here, we report an enantiornithine specimen from a new locality in the Upper Cretaceous La Colonia Formation of Patagonia, Argentina. Although mammals and other… Expand

Reinterpretation of Paleoazolla: a heterosporous water fern from the Late Cretaceous of Patagonia, Argentina.
TLDR
The presence of two megaspores in the megasporangium of Paleoazolla exposes serious gaps in the current knowledge on the evolution of monomegaspory in heterosporous water ferns, a fact that emphasizes the need of including fossils within phylogenies to elucidate patterns of character acquisition among water f Ferns.

A Large Ornithurine Bird (Tingmiatornis arctica) from the Turonian High Arctic: Climatic and Evolutionary Implications
TLDR
It is proposed physiological differences in ornithurines such as growth rate may explain their latitudinal distribution especially as temperatures decline later in the Cretaceous. Expand
A new Late Cretaceous snake from Patagonia: Phylogeny and trends in body size evolution of madtsoiid snakes
TLDR
A comprehensive phylogenetic analysis recovers Madtsoiidae as a basal ophidian lineage and the new snake as sister to a clade of mostly big-to-gigantic taxa, providing insights into early stages and evolutionary trends towards madt soiid gigantism. Expand
Late Cretaceous Aquatic Plant World in Patagonia, Argentina
TLDR
A reconstruction of the aquatic plant paleocommuniy is provided based on the distribution of the fossils along a freshwater horizon within the La Colonia Formation, constituting the first reconstruction of a Cretaceous aquatic habitat for southern South America. Expand
New marsileaceous fossils from the Late Cretaceous of South America and a reevaluation of Marsileaceaephyllum
TLDR
The co-occurrence of Molaspora lobata with an extinct marsileaceous leaf form fits a pattern wherein Cretaceous Regnellidium-like megaspores are associated with or found in situ within Marsileaceous macrofossils that display a variety of morphologies. Expand
Erratum to: New marsileaceous fossils from the Late Cretaceous of South America and a reevaluation of Marsileaceaephyllum
Herein we report new macrofossils and associated microfossils representing the aquatic fern family Marsileaceae from the Campanian to Maastrichtian Cañadón del Irupé locality, La Colonia Formation,… Expand

New South American record of the Cretaceous–Paleogene boundary interval (La Colonia Formation, Patagonia, Argentina)
Abstract The La Colonia Formation is an Upper Cretaceous to Paleogene shallow marine sedimentary unit in Chubut Province (Patagonia), Argentina that preserves important vertebrate and plant fossils.… Expand
The making of calibration sausage exemplified by recalibrating the transcriptomic timetree of jawed vertebrates
TLDR
The present work reevaluate all thirty calibrations in detail, present the current state of knowledge on them with its various uncertainties, rerun the dating analysis, and conclude that calibration dates cannot be taken from published compendia or other secondary or tertiary sources without risking strong distortions to the results.

Juvenile Birds from the Early Cretaceous of China: Implications for Enantiornithine Ontogeny
TLDR
The skeletal morphology of three nearly complete early juvenile avians from the renowned Early Cretaceous Yixian Formation of Liaoning Province in northeastern China are reported on, suggesting that fledging occurred very early in ontogeny, thus supporting a precocial or highly precocial strategy for enantiornithine hatchlings.

The discovery of a new bird from the Lower Cretaceous Yixian Formation, Liaoning Province, China, which represents a new species, but bears similarities to Hongshanornis longicresta from the same formation of Inner Mongolia, and represents a clade of specialized ‘shorebirds’ whose elongate hindlimbs indicate ecological adaptations different from those of other Jehol ornithuromorphs.
