Data from: Modelling enrolment in Cambrian trilobites
- 负责人：
- DOI：
- doi:10.5061/dryad.s29j7
- 摘要：
- on X-ray microtomography scans of complete enrolled specimens from the Cambrian, we created three-dimensional (3D) computer models to assess the kinematics needed to achieve
Data from: Adaptive credible intervals on stratigraphic ranges when recovery potential is unknown

- 摘要：
- ides reasonable point estimates of the true extinction in a variety of situations. We demonstrate the method using a dataset of the Cambrian mollusc Anabarella.
