Cenozoic megatooth sharks occupied extremely high trophic positions
Trophic position is a fundamental characteristic of animals, yet it is unknown in many extinct
species. In this study, we ground-truth the 15N/14N ratio of enameloid-bound organic matter …

Phanerozoic parasitism and marine metazoan diversity: dilution versus amplification
Growing evidence suggests that biodiversity mediates parasite prevalence. We have
compiled the first global database on occurrences and prevalence of marine parasitism …

Trilobites as hosts for parasites: from paleopathologies to etiologies
Extant marine arthropods are afflicted by a variety of parasitic diseases making it plausible
that extinct trilobites also had a variety of parasites. Direct evidence in the form of preserved …
