Foster Preparation Lab at South Dakota Mines

Foster Preparation Lab at South Dakota Mines The Foster Preparation Lab specializes in the preparation and conservation of South Dakota vertebrat The Foster Preparation Lab is housed within the James E.

Martin Paleontology Research Laboratory on the South Dakota School of Mines and Technology campus. Students and volunteers learn about the importance of fossil resources through hands on experience, learning current conservation and preparation techniques. Visitors are able to watch paleontologists remove local South Dakota fossils from rock and prepare them for scientific research, or for displa

y at the Museum of Geology. The Foster Prep Lab accepts qualifying volunteers to work in the lab. Are you interested in getting to work with real fossils, and want to learn how to clean fossils from rocks? Contact us today to get started!

A new addition to the Museum of Geology exhibits!

The museum has been working for the past year to update a few of the cases in our timeline display that wraps around the central mounts. This has been a collaborative effort between the fossil preparation team and the exhibits team. Darrah Steffen, our Assistant Director, led the charge on this project with planning changes, writing exhibit text, and selecting fossils. Thacher Dramstad (left in photo) has been filling in for Darrah while she’s on maternity leave as our Exhibits and Outreach Specialist.

A number of students and volunteers have put in countless hours in the lab to get specimens ready for display. Isaac, Caleb, James, Elizabeth, DJ (center in photo), and Gracie (right in photo) have all contributed to specimens going on display recently.

The specimen highlighted in this post is a Triceratops brow horn. It was prepared by a volunteer years ago, but never fully cataloged. When Darrah decided she wanted to add in a Hell Creek section to our timeline cases that highlighted the time of the dinosaurs, she knew from the start that Triceratops had to be featured. Her and I looked all over collections for a triceratops horn, and found one that was in good enough condition for display but needed significant prep work. In the time that I was working through the different exhibits projects in the prep lab, I eventually came across the horn pictured here, in great condition and only in need of a new jacket. So this beautiful horn was cataloged and chosen for exhibit instead.

I especially wanted to highlight this specimen because you never know what can be sitting in a museum collection waiting to be displayed, researched, and discovered. Also, for me, this new addition to the Hell Creek case marks the beginning of the end of some of the major exhibit updates we’ve been working on. There are still a few more projects in the lab that need to be finished, but now the empty spaces in our timeline have largely been filled.

The prep lab has been staying busy this summer!

I have two preparation assistants helping me out this summer in the lab. The first is DJ who has been working quickly through projects from Badlands National Park. Here he is working on a rhino skull and the second photo is of a storage jacket we completed this morning for an Archaeotherium skull.

My second assistant is Gracie, she’s been working on a fairly well complete mosasaur skeleton pictured in the last photo. There are multiple more boxes just like those two. Having more help in the lab has significantly increased productivity. More hands means more projects getting completed and ready for research or display!

Fish update! 🐠

You may not recognize this preparation project from the first photo, but this two year prep project containing the tail of a Xiphactinus has been completed. Pictured first is Isaac, one of the lab student workers, with his completed project. The following photos showcase the progress of this project throughout its time spent in the lab. This is a great example showing how much time fossil preparation can take, but patience and dedication can help create a fantastic end result. This specimen is now in our Vertebrate Paleontology collection here at the Museum of Geology awaiting future research.

The Vertebrate Fossil Preparation course is back in full swing this semester! The students taking the class get to learn about a variety of tools and techniques for fossil preparation in an actual prep lab using simulated prep projects. The photos shown are of last week when the students learned how to use a variety of air scribes to remove fossils from plaster. This week in lab they are reassembling broken terracotta pots using one of the more common adhesives used in prep labs, Paraloid B-72 mixed with acetone in a 50/50 ratio.

This class can help future preparators learn many of the standard tools and techniques of fossil prep. It can also give a well rounded learning experience to students who pursue other areas of paleontology.
