New Phytologist, EarlyView.Morphospace position and phylogenetic placements of Trimeriantha monopolyada. Summary Floral structure is a key aspect of angiosperm diversity. Recent research revealed that significant floral disparity was already present in the Cretaceous. However, our understanding of early floral diversity remains limited, as it is directly dependent on the fossil ...

Sedimentology, EarlyView.ABSTRACT Deciphering sediment provenance is essential to understand depositional patterns and dynamics. This question is particularly important in archaeological contexts to constrain the sedimentological history of unearthed material—an information critically needed, for example, to estimate the age of the deposits—or to apprehend sediment movement ...

Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade
Biological Reviews, Volume 101, Issue 4, Page 1760-1778, August 2026.ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...

Presence of vertebrate coprolites from the Alagoas Basin, Lower Cretaceous [PDF]
Boletim do Museu Paraense Emílio Goeldi. Ciências Naturais, 2010 Coprolites collected from sedimentary rocks of the Maceió Formation, Alagoas Basin are analyzed for the first time. The specimens consist of two complete coprolites of cylindrical morphology that are preserved in commonly fluidized medium- to coarse ...

Geoarchaeology, Volume 41, Issue 3, May/June 2026.ABSTRACT The archaeological site of Las Estacas Cave (NW Tenerife, Canary Islands) preserves some of the earliest human occupations in Tenerife, dating to the 2nd century CE, spanning the entire pre‐European time range up to the 15th century. Using soil micromorphology, this study applies a geoarchaeological approach to reconstruct site formation ...

Enterobius vermicularis: ancient DNA from north and south American human coprolites
Memorias do Instituto Oswaldo Cruz, 2003 A molecular paleoparasitological diagnostic approach was developed for Enterobius vermicularis. Ancient DNA was extracted from 27 coprolites from archaeological sites in Chile and USA.
