Virtual habitats, fossil preservation, and estimates of dinosaur biodiversity in the Cretaceous of North America

Alfio Chiarenza
The archive of fossils and the sedimentary rocks that enclose them preserves a long record of climate change and associated fluctuations of biodiversity. However, this record is biased, and considerable efforts have focused on developing sampling methodologies and statistical treatments to mitigate for bias in a way that will allow us to understand how biodiversity has changed through time. The methods presented here attempt to account for the problem of data absence and spatial heterogeneity...
