Darwin Core (DwC) Hour #13 is almost here: *The Problem of Time: Dealing with Paleontological and Zooarchaeological Specimens in Darwin Core https://www.idigbio.org/content/darwin-core-hour-problem-time-dealing-paleontological-and-zooarchaeological-specimens-darwin!*

*When*: *Tuesday, 24 April 2018*

*Time*: *1pm Eastern / 5pm UTC*

*Where*: https://idigbio.adobeconnect.com/room

The temporality of specimens is a quintessential piece of information that undeniably adds research value. Part of what makes specimens so invaluable is the fact that they represent life in a certain form at a particular place and time. However, there are some complications when it comes to reporting and comparing collection dates and the ages or chronology of ‘modern’ specimens to those from paleontological or zooarchaeological relevant time frames. This Darwin Core Hour aims to take a deeper look at some of these complexities, to begin community discussions of how these important data should be portrayed in Darwin Core, and to provide a starting point for these discussions by introducing the Chronometric extension for Darwin Core that is currently under development.

However, there are some complications when it comes to reporting the collecting dates versus the ages or chronology of ‘modern’, paleontological, and zooarchaeological specimens, as well as making meaningful comparisons across represented time frames (e.g., modern, archaeological, paleontological).
