The Influence Of Spines On Predation And Survivorship Of Devonian Brachiopods, Broc S. Kokesh

Undergraduate Research Symposium 2016

Brachiopods are small animals that live on the seafloor and are abundant in the Devonian fossil record (420 to 360 million years ago), making them excellent subjects for studying evolution in ancient marine environments. Some species sported large spines that cover their exterior surfaces, although these spines are typically broken off during fossilization. Paleontologists have hypothesized that these spines developed as an evolutionary response to predation, yet few studies have tested this idea due to the scarcity of specimens with intact spines. Recent work has been able to get around this problem by examining injury markings caused by predators that …
