Fabaceae is one of the most diverse angiosperm families and is distributed across the globe
in a variety of environments. The earliest evidence of the family, previous to this work, was …

Plants and insects are two of the more diverse and abundant organisms in terrestrial
ecosystems. The fossil record of plant-insect interactions offers crucial insights into the …

We present new data based on physiognomic analysis of the Olmos Formation leaf flora,
indicating it represents a paratropical rainforest with an inferred mean annual temperature …

Unlike other geological elements with relevance to geoheritage, coal deposits have not
been properly studied in Mexico. In the Sabinas Basin, NE Mexico, there are many coal pits …

Abstract The Olmos Formation (upper Campanian) is located in the Sabinas Basin in
northern Mexico. It represents a deltaic-fluvial system, and it is known by its abundance of …

We compiled the fossil record of the heterosporous water ferns (Salviniales) including macro-
and microfossils from South America and the Antarctic Peninsula. Both extant families …

We describe a water fern spore assemblage from the Maastrichtian La Colonia Formation,
Chubut Province, Patagonia, Argentina. The assemblage includes three species of Azolla …

The fossil record of Marsilea is challenging to assess, due in part to unreliable reports and
conflicting opinions regarding the proper application of the names Marsilea and …

Premise Undoubtedly, fossils are critical for understanding evolutionary transformations in
deep time. Here, we reinvestigate the microspores and megaspores of Paleoazolla …

The present study reports unique leaflets of a semi-aquatic fern (Marsileaceae) preserved in
mid-Cretaceous amber from Myanmar, and further describes the new species …
