LET US PREY: SIMULATIONS OF GRAZING TRACES IN THE FOSSIL RECORD (2008)
Trace fossils are the only direct record of the behavior of ancient organisms. They thus provide critical indications of the early evolution of sensory systems and of the behavioral response to...

Understanding the extent to which the reported fossil record reflects biological history, rather than preservational artifacts or other biasing factors, remains one of the central issues in the...
Are the most durable shelly taxa also the most common in the marine fossil record? (2005)

This paper tests whether the most common fossil brachiopod, gastropod, and bivalve genera also have intrinsically more durable shells. Commonness was quantified using occurrence frequency of the 450...

Previous studies of overall arthropod disparity have compared Cambrian and Recent biotas, without considering taxa of intermediate age. This study explored morphological diversity among Carboniferous...
A multiplicative multifractal model for originations and extinctions (2001)
Recent works have suggested that the fossil record exhibits a fractal structure; i.e., that processes, such as extinction, follow a power-law size distribution and their time series show a 1/f power...
