Ep177: Cambrian Fecal Revolution

The evolution of guts brings with it the evolution of faeces & as animal life radiated into the #Cambrian the poop began to pile up. In this episode, we learn of the effects this had on the planet.

Online now: The Cambrian fecal revolution: Fueling the Cambrian Radiation
The Cambrian fecal revolution: Fueling the Cambrian Radiation
Coprolites—fossil material extruded from an animal’s digestive system—represent a rare insight into trophic interactions in deep time. However, while the first animals appeared about 600 million years ago, the first coprolites are only observed in the earliest Cambrian. Conversely, in modern oceans, fecal pellets are an important part of the particulate organic carbon in the water column and the global flux of organic carbon to deep water. In this review, we analyze the impact of the advent of fecal matter on the Cambrian Radiation by examining coprolites, analyzing animal biology, and contextualizing this through the role of fecal pellets in the oceanic nutrient cycle. We illustrate the central position of coprolites in driving the Cambrian Radiation.

Hi, does anyone have an idea what museum might have had labels like the one on this specimen. We're trying to return a bunch of old loans, and this specimen has no information. It's a receptaculite, maybe that helps.
