ENHYDROSS: A New Mechanistic Model Supports the Trans-Oceanic Dispersal Capability of Terrestrial Vertebrates. [PDF]
Ecol EvolWe introduce ENHYDROSS, a new mechanistic model that uses optimal swimming speed and minimum cost of transport to estimate maximum dispersal distances and durations for vertebrates, enabling assessment of long‐distance oceanic dispersal potential. Applied to a range of extant and extinct animals, the model's estimates generally align with observed data;

The evolution of reproduction in Ediacaran-Cambrian metazoans. [PDF]
Biol Rev Camb Philos SocABSTRACT The evolution of reproductive style is a fundamental aspect of metazoan life history but has not been explored holistically through the Ediacaran–Cambrian rise of metazoans. Recent molecular clock analyses based on only unequivocal metazoan fossil calibrations suggest that Porifera were present by at least 590 million years ago (Ma), all major

The Gemmellaro Collection: first record of an anomuran from the Tithonian of Sicily, Italy
BSGF - Earth Sciences Bulletin, 2017 A recent field trip to Sicily and an examination of decapod crustacean collections at the Museo Geologico G.G. Gemmellaro in the centre of Palermo, Sicily (Italy), has demonstrated that most of the anomuran and brachyuran material described by Gemmellaro
