As part of the AMNH Paleontology internship, we are keeping a blog on the progress of the rehousing project. The interns are updating the blog weekly and taking turns writing entries. Below is this week's entry, penned by yours truly. For more updates from the Paleointerns, check out the entire blog here.
This past Monday we began our first post-training week and settled into the schedule we will have the rest of the summer - rehousing on Monday, Wednesday, Friday, georeferencing on Tuesday, and elements descriptions on Thursday.
Rehousing
As we become more familiar with rehousing and fossil handling techniques, we're settling into a solid pace of pulling, rehousing and returning a few cart-fulls of specimens to the collections each day. We completed nearly 50 rehousings during the past week.
One highlight was figuring out, with guidance from Carl and Ivy, what to do with the tray of bones set in a large plaster block that we'd mentioned in the previous blog post. Such an arrangement is known as a plaque mount and is intended for display. Since the plaster block is far too large to fit in any of the boxes we have (it takes up nearly the entire drawer), we used tri-rod to stabilize it in the drawer, and if we come across such a mount where parts of the fossil are raised above the top of the tray, we'll make a choroplast riser to protect the bones from other trays scraping on top of them.
A second challenge that arose came not from a fossil, but from a fossils' documentation. Some specimens had notes with them written on newspaper over 100 years old - the oldest so far is from 1898. To keep these notes - which have become pretty tattered - from further deteriorating, we used archival quality tape to mend rips and reinforce any part that seemed prone to tears.
We’re making a big dent in the type collection - or it certainly feels that way. The process is going much more smoothly and we’re continuing to find our niches.
Georeferencing: Where in the world?
On Tuesday we had a briefing with Chelsea about our first round of georeferencing from the week before. We got the chance to ask her about any problems we had run into and also share any helpful hints we'd figured out during our first batch of localities. Since the objective of georeferencing is to take information about the location of a specimen's origin given by the excavator and plot it on a current map - we need to find the country, state/region, and county/division of the excavation site.
One challenge we ran into is that some territorial boundaries have changed since the fossils were excavated. For example, we were working on a locality listed as "Bugti, India" - excavated in 1923 - and weren't making much progress until we figured out that the excavation took place in what is today Pakistan.
We divided up the remainder of the master list of localities amongst ourselves. After filling in the territorial information, we'll go back and find the latitude and longitude - using field notes, shipping record, and Google Earth. We'll have plenty more questions for Chelsea when we get to that stage.
