Paleontologists have long reconstructed phylogeny using comparisons between fossil record and recent taxa. On the other hand, biologists reconstruct phylogeny using molecules to produce a tree which they constrain using fossils and geographic events to provide estimates for phylogenetic events. Taking both extant and extinct species into account for systematic revisions is essential for biologists and paleontologists. In this paper, I demonstrate example of how paleontological methods, such as preparing thin sections and using x-ray and CT scans can also be applied to extant invertebrates. I provide further discussion of how robust integration between paleontologists and biologists is rewarding to both disciplines.
