The latest shallow-sea isocrinids from the Miocene of Paratethys and implications to the Mesozoic marine revolution
Abstract The predation-driven Mesozoic marine revolution (MMR) is believed to have induced a dramatic change in the bathymetric distribution of many shallow marine invertebrates since the late Mesozoic. For instance, stalked crinoids – isocrinids (Isocrinida) have undergone a striking decline in sha...
