Tracking Information

One thing I never fully appreciated before this job was the way specimens are labeled. Specimens may become dissociated from their original field labels; paper labels can be eaten by silverfish and bookworms; floods can make ink run; fires can destroy everything. I have become accustomed to a variety of different labeling techniques over the last four years, and today I want to share some of these.

Some times localities are written directly on specimens. A great thing about this method is that the locality information is retained even if the paper label is lost. One problem is that these types of things are often not very specific.
Take this coral for example. It is from Gothland (or Gotland). Gotland is an island off the coast of Sweden. It is particularly well known for its Silurian fossils. It is also over 3000 square kilometers.

Some times extensive information is inscribed directly on the fossil. This bivalve has been inscribed with its name, locality and provenance. All of this information is still legible too (which doesn't always happen when things are written in pencil).

Lesson to be learned to today: take copious notes. You may think it is too much information, but any clue can be helpful in determining where a fossil came from, and how it arrived at the museum. While writing on a specimen is often impossible, adding at least a town name (or an island) can be helpful in narrowing down the original locality. Write everything down in a notebook as well. When you donate your collection to the museum, give them your notebook too. We'll promise to keep it away from the book lice!

Strophalosia tenuispina, my first photograph

I thought it fitting to begin this blog with one of my earliest specimens here at the Peabody Museum. This is the very first photograph of a brachiopod that I took. It was part of a three year NSF-funded project to digitize many of our specimens. This is a Strophalosia tenuispina from the Baral Nala, SW of Amb in the Salt Range Mountains of Pakistan. It is Permian in age. The strophalosiids were commonly attached to hard substrates, either by cementing one valve directly to the substrate or wrapping their spines around it.

Who I am and what I do

Following the lead of several colleagues here, the Division of Invertebrate Paleontology is starting a blog. Much like the Division of Vertebrate Zoology's fabulous blog (The Life You (And I) Never Knew) this blog will present a glimpse into the Division of Invertebrate Paleontology here at the Yale Peabody Museum. Our specimens are spread across three buildings and are categorized into three different collections. This blog will focus on our Systematic Collection with which I work most closely.
