Predatory behaviour on Ostracoda: spatial analysis of drill-hole distribution in relation to shell size and ornamentation onlinelibrary.wiley.com/doi/10.1111/... #FossilFriday @mnritter.bsky.social @ufrgs.br

Top left: map showing Valparaiso and Santiago (red diamonds) in Chile (shaded grey) and the study region outlined in red. To the right are two black and white photographs of drilled left valves of ostracods from the Miocene Navidad Formation. Upper image is Cytherella with drill hole trace Oichnus simplex; lower image is Apatihowella with hole trace O. paraboloides. Each photograph has a scale bar in the lower left corner, which is 100 microns.
Lower right plot is a frequency distribution for outer drill hole diameter (vertical axis), with trace O. paraboloides on the left, in red, and O. simplex on the right in blue.
Blue rectangle at the top in the centre is a cover image from the journal Palaeontology.

Sediment accumulation rate (how quickly the sea bottom is covered by new sediment) is the main predictor of the temporal resolution of (sub)fossil assemblages, a key property to address both paleontological and ecological questions. www.pnas.org/doi/10.1073/...

Our most recent paper published in Earth Science Reviews presents a comprehensive and quantitative survey of literature data on drilling predation in Ostracoda. So proud of my first Ph.D student, Camila Cruz. Check it out. In collaboration with @paleoadiel.bsky.social doi.org/10.1016/j.ea...

This past week, @paleodanae.bsky.social and I have conducted the Paleontology of Marine Cenozoic Molluscs session at the World Congress of Malacology. Thanks to all for this marvelous opportunity.
