The Division of Vertebrate Paleontology has at least one fossil collecting session per year that uses volunteer assistance. This will generally be during the drier and cooler times of the year; spring and/or fall. Age limits and physical requirements will vary depending on the conditions at the particular fossil site we are working.
We are currently working on a large-scale, extensive excavation at the Montbrook fossil site. The Hemphillian Montbrook Site is about a 40-minute drive south of Gainesville, near the town of Williston in Levy County. Summaries of the past field season at the Montbrook fossil site can be found below.
Montbrook is very productive, and almost all volunteers will find some fossil specimens on their first day. The most commonly found fossils are bones from the shell of freshwater turtles and vertebrae, spines, scales, and skull bones of fish, including gar, catfish, snook, and drum. Fossils of alligator, birds, and mammals are also found, but less frequently. Our most common mammal is the gomphothere, an elephant relative. Want more info about Montbrook?

SPRING 2019 DIGGING SCHEDULE
We will dig at the Montbrook Site starting March 1 and continue daily until March 28, 2019. Volunteers who worked at the site during 2018 or the fall of 2017 can begin to reserve dig dates starting February 1. Those who are current museum volunteers and/or who dug at the during the Fall 2018 Montbrook dig just have to fillout and send in this form. No application form is needed. Those who dug at the Montbrook site during the Fall 2017 or the Spring 2018 seasons must fill out both an application form and a form to reserve dig dates. There are separate application forms for adults (18 years and older) and for those whose age in March 2019 ranges from 15 to 17.
For those interested in volunteering who have either never dug at the Montbrook Site, or who dug with us prior to the Fall 2017 season, we will begin to take your reservations on February 8.
There is no cost to volunteer. However, if you wish to contribute money to help us maintain our annual volunteer fossil digs and to process and store the collected fossils, you can use this secure link https://www.uff.ufl.edu/OnlineGiving/FundDetail.asp?FundCode=008465. Donations through the UF Foundation are tax deductible.

Fall 2016 Fall Season Summary
Thanks to our unusually dry weather, we only had 3 days rained out, two of those because of Hurricane Matthew early in October. Therefore, we had even more possible days to excavate fossils than anticipated. Collectively 168 different volunteers participated in the dig this season, contributing over 1,800 hours of work at the site and finding many thousands of fossils, including the first skull from a carnivore found at Montbrook. We thank again all those who came out and worked with us, in good weather or bad, to make this dig another great success.
Twenty volunteers worked at the site for 20 or more hours (some much more), and we want to especially acknowledge their efforts. They are William Buhi, Suzanne Conner, Ella Cooney, Jerry Donaldson, David Evans, Alexander Gerasimov, Mackenzie Goode, Kara Ericson, John Helling, Cindy Lockner, Sheila Lucas, Mary Lynch, Amanda Ploener, Peter Roode, Sharon Shears, Karen Stansell, Dean Warner, Lee Williams, Nancy Williams, and Patricia Williams.

Carol Sewell, William Sewell, and Susan Harris volunteered over 100 hours each!
Thank you all so much for your dedication to the fossil site and to the property landowner for allowing us such access!
Some highlights from this season:
The very first day of digging following the summer break, a baby gomphothere skeleton was exposed.Since then it’s been Gomph-A-Palooza.
We celebrated our two-year anniversary, expanded the pit, prepared plaster jackets for the public in the Florida Museum’s 100-Year Anniversary exhibit, cataloged our 10,000th specimen, and hosted a tour of the site for our youngest group yet, the Earth Sciences class of East Marion Elementary.
We plan to dig 84 days for the Spring 2018 season. Imagine the possibilities!
Spring 2018 Season Summary:
208 volunteers, 51 students for course credit, 14 teachers for professional development, and 38 Florida Museum staff devoted a grand total of 4,977 hours to Montbrook this season! The Spring 2018 digging season ran for 90 days, from Friday, January 19th until Sunday, May 13th. Many different groups joined us, including students from St. Olaf College in Minnesota, UF students enrolled in Jonathan Bloch’s Florida Vertebrate Paleontology course and Laura Cotton’s Invertebrate Paleontology course, exhibits staff of the Florida Museum, High school students of the Gainesville Youth Fossil Club, and members of the Florida Paleontological Society.

We removed around 90 plaster jackets just this Spring and the close of the season brings us to around 30,000 identifiable fossil specimens total for Montbrook. During the final 7 days of digging this season, Montbrook gifted us with rare and abundant mammal specimens. These include 2 mandibles, 1 skull, and 1 palate of our gomphothere (Rhynchotherium) and 2 rhino (Teleoceras) skeletons, one a juvenile and the other a young adult, both with associated mandibles!
Thanks so much to everyone who has volunteered their time at Montbrook! None of this would’ve happened without your help. A special thanks to those volunteers who helped with the final push to remove those last large specimens and who worked over 30 hours this season. These people include (in alphabetical order): William Buhi, David Cox, Joshua Doby, David Evans, Joseph Fulco, Ben Grubbs, Susan Harris, John Helling, Daniel Ibison, Maya Ibison, James Kendrick, Sharon Lord, Margaret Messineo, Paula Mitchell, Robert Mitchell, Garrett Munger, Steven Munger, Andrew Puckett, Carol Sewell, William Sewell, Sharon, Shears, Emily Sonnenberg, Maryan Stubbs, , Dean Warner, and Judith Wilbanks. Susan Harris wins the award for most volunteer hours at 152.25 this season; this is not including the hours she also spends preparing fossils back at the museum! Thank you Susan! Second place goes to Garrett Munger at 123.25 hours this season, which is also incredible because he is in high school and plans to volunteer in the collection this Summer! Also a huge thank you to all Florida Museum vertebrate paleontology staff and students who make this possible!

Fall 2018 Season Summary:
This fall we excavated at Montbrook from November 7 to December 9. One hundred ten volunteers worked a total of 1,426 person-hours in 24 days! Museum staff and UF paleontogy students dug for an additional 715 hours. This despite unusually hot weather at the start of the seaon and cold, rainy days towards the end.
Our top volunteers, who each worked 20 or more hours were: David Cox, John Freund, Susan Harris, John Helling, Vickie Jacobs, Larry Jensen, Sharon Lord, Ken and Tammy Marks, Melanie Masdea, Donna McCullough, Garrett and Steven Munger, Judy Peterson, Deborah Poulalion, Arnold Sacco, Carol and Bill Sewell, Dean Warner and Michele Wilbanks. Like last spring, Susan Harris narrowly surpassed Carol and Bill Sewell to claim top honors for most hours worked (71.5). While many of those names are holdovers from prior seasons, it is also great to be able to add some new names to the top volunteers list. Thank you all so much for your dedication to the fossil site and to the Hodge family for allowing us continued access to the site and working to solve our drainage problems!
Some highlights from this season:
- Sue Tennant found a nearly complete lower jaw of the lynx-like cat "Felis" rexroadensis. It is more complete than any previously known specimen of this species from Florida. Previously the species was known from Montbrook by just a single isolated tooth and a tibia.
- Michele Wilbanks discovered a partial skull of the peccary Protherohyus brachydontus. This is the second skull of this species found at Montbrook, and just the third known from Florida. Its relative completeness won't be known until it is prepared out of its plaster jacket, but most of the teeth are present.
- On the very last scheduled digging day, Jaiden Torres collected a nearly complete bird leg bone that our avian paleontologist David Steadman has identified as the first fossil from an ibis to be found at Montbrook, and a possible new species.
- Another concentration of proboscidean fossils were collected within a relatively small area about 5 meters long and 4 meters wide. These included two skulls, one with both tusks and the other with one of its tusks, and three sets of paired right and left lower jaws. All three of the mandibles appear to be relatively complete and lack much of the crushing that has distorted many of the previously collected specimens. One of the skulls and two of the mandibles are from the gomphothere family of proboscideans; the identity of the others awaits preparation to reveal their teeth. All five specimens were initially discovered by volunteers. Congratulations go out to Susan Harris, Steven Munger, Larry Jenson, Cryatal Diaz and Ryan Thompson for finding these great specimens.
- A total of 40 plaster jackets were made and successfully collected this season. They ranged in size from that of a coffee cup for a skull of the turtle Trachemys to a six-foot-long monster containing a proboscidean skull that had to be carried out of the site by one of the excavators.
