27G: Georgia’s Decapod Fossils
By Thomas Thurman
16/Jan/2026
Decapods are a large order of crustaceans which includes crabs, lobsters, crawfish, shrimp and prawns. They aren’t well represented in Georgia’s fossil literature with only half a dozen or so reported. Worse, a surprising number of these list decapod as commonly occurring without going into detail or exploring which species are present.
You gotta dig a little deeper. Surprisingly many Southeastern natural history museums don’t publish a database on 0their collection. Thankfully, the Florida Museum of Natural History (FLMNH) offers a splendid database of their invertebrate collection. I’ve been in the field with Dr. Roger Portell, the Museum’s Invertebrate Collection Director, and enjoyed his assistance many times on this website’s pages. He’s a good man & excellent paleontologist. FLMNH houses 115 Georgia-sourced specimens ranging from the Late Cretaceous to the Late Pleistocene. This gives Georgia about 125 total specimens.
Here’s a link to the FLMNH database.

Preservation: the shells of decapods are formed by chitin which is rarely preserved, it’s not as strong, rigid, or durable as the calcium shells of other shelly animals. Because of this the fossil record everywhere is very sparse.
Note; On Sunday, 18/Jan/2026, Dr. Burt Carter reminded me that carapace composition is often more complex than my explanation.
"And, like a number of other crabs (maybe Lophoranina?), the carapace of, say, stone crabs is fortified with a lot of High-Mg calcite."
Dr. Gale Bishop is an authority on this. He’s a Professor Emeritus at Georgia Southern in Statesboro. In 1986 he published the paper Taphonomy of the North American Decapods. Taphonomy is the process of fossilization. The paper attached for download at the base of this page. All the papers discussed on this page are available below.

Here I need to recognize Chet Kirby and his family. Chet is an active, respected amateur paleontologist on the Georgia coast where he has amassed a large collection of important specimens in an area with highly challenging stratigraphy.
Kirby is well known among many professionals. There are 39 decapod specimens in the FLMNH which were collected by Chet Kirdy and his family. No small feat. That is a large portion of Georgia’s whole decapod fossil record from the efforts of one family. Chet Jr. is a member of our Georgia’s Fossils Group on Facebook.
Other Records
The Smithsonian National Museum of Natural History also maintains a large collection of decapods but none from Georgia.

The Paleobiology Database shows half a dozen records, some Cretaceous species from West Georgia and some Oligocene species from the Bainbridge area. The Bainbridge report which seems to be a mistake. This is Lophoranina georgiana which the Paleobiology Database lists as reported by Mary Rathbun in 1935 from the Glendon Limestone in Bainbridge.
There are two issues with this report,
- In 1935 Mary Rathbun report is for Ranina georgiana from the Glendon Limestone. We’ll look at this presently.
- In Georgia, the Glendon Limestone only occurs in Pulaski County, well northeast of Bainbridge.
- But Lophoranina georgiana is correct, the decapod species Ranina georgiana was reassigned in 2010 as Lophoranina georgiana.
According to Paul Huddlestun (Bulletin 105, 1993);
The Glendon Limestone was named by Cooke (1918) for limestone of Vickeburgian age that overlies the Marianna Limestone in Alabama. In Georgia, the only known occurrence of the Glendon Limestone is in a bluff on the Ocmulgee River near Hawkinsville in Pulaski County.

Note; All that said; Dr. Burt Carter correctly reminds me that paleontology and stratigraphy, as sciences, have matured in the last 90 years since Rathbun's paper.
In a 18/Jan/2026 email Burt points out.
"In the 30's people were thinking about "Formations" almost like time units. Cooke called every Oligocene limestone east of west Alabama "Suwannee" because it was in roughly the right stratigraphic position."
"So when Mary Rathburn said she had something from the "Glendon" near Bainbridge she was probably talking about what Cooke called the "Flint River", which he took to be a little older than the Suwannee (remember, he called it "middle" Oligocene). In western Alabama and Mississippi the Glendon is the most prominent non-Marianna Limestone, so she was just saying it was in that position and wasn't Marianna.
I"'ve heard Paul call the residuum in the Bainbridge area "Glendon/Mint Springs residuum", but not in print."

Mary Rathbun 1935
In 1935 Mary Jane Rathbun, a native of Buffalo New York, published large report on Atlantic and Gulf Coast plain crustacean fossils. She was an invertebrate zoologist specializing in crustacea who went to work for the Smithsonian in 1884 and remained with the institution until her death in 1943. She described more than a thousand species & subspecies in her career. However, her 1935 report only mentions two from Georgia: A Cretaceous species (Callianassa mortoni) and an Oligocene species (Lophoranina georgiana reassigned from Ranina georgiana).

Callianassa mortoni Ghost Shrimp
- Typically, only claws are found, and these can be up to an inch long.
- Males and female claws are different
- Juveniles and adult claws are different.
- Late Cretaceous
- Chattahoochee River at Blufftown, Stewart County; Eutaw formation
- Reassigned as Protocallianassa mortoni by G. Bishop in 1983
- Reassigned as Mesostylus mortoni by Schweitzer and Feldmann in 2012
- Widespread distribution; New Jersey, Deleware, Maryland, Georgia, Tennessee, Alabama, Mississippi, Arkansas & Texas.
Lophoranina georgiana (Frog Crab or Spanner Crab)
- Early Oligocene
- Glendon Limestone
- Hawkinsville is the only outcrop of the Glendon Limestone in Georgia.
- Rathbun included an illustration of some kind for this species on page 98 of her report, but every digital copy I found of the paper ended at page 80.
Bishop & Whitmore 1986
In 1986 Gale A. Bishop with the Institute of Anthropology and Parasitology at Georgia Southern and Janet L. Whitmore with the Museum of Geology at South Dakota School of Mines and Technology published the extensive report The Paleogene Crabs of North America.
In 1986 Gale A. Bishop with the Institute of Anthropology and Parasitology at Georgia Southern and Janet L. Whitmore with the Museum of Geology at South Dakota School of Mines and Technology published the extensive report The Paleogene Crabs of North America.
Again, they reported only a few Georgia occurrences but those suggests populations are present. To quote Bishop and Whitmore paper.
Tivola Limestone
Decapods from the Tivola Limestone
The Tivola Limestone is a coarse bioclastic coquinoid limestone which becomes clayey enough in places to be a marl. (This is true in the eastern exposures like Washington County. Its western exposures tend to be a purer limestone, up to 98%, with occasional sand content.) Clasts consist primarily of bryozoan fragments but include abundant oysters, numulitid foraminifera, sand dollars, and mollusk steinkerns. (To the east, sand dollars & scallops dominate and oysters are rare.) Decapod remains, usually disassociated and broken, are common throughout the limestone at the Medusa Portland Cement quarry and the nearby Dixie Limerock Quarry. (Houston County) Many remains are represented by external carapace molds at these localities. Taxa present are Calappilia brooksi; Ocalina foridana, and Callianassa inglistris.

The Tivola Limestone is named for the extinct village of Tivola which once stood about 6.5 miles due east. It’s worthwhile to note that neither Huddlestun & Hetricks 1986 report (Bulletin 95) nor Pickering’s 1970 paper (Bulletin 81) report any crustaceans in the Tivola, and both researchers looked rather closely at the paleontology.
Twiggs Clay
Bishop and Whitmore report that parts of the huge, thick-shelled claw of Callianassa occurs in the Tivola of Houston County. A claw evolved for crushing. They pass on a 1974 report from Paul Huddlestun of a suite of filled burrows in the overlying Twiggs Clay “which contain many claws of Callianassa” (species unknown). Bishop and Whitmore argue that the occurrence of Callianassa claws in the burrows strongly suggest that Callianassa excavated the burrows.

Freile and Fuks 2001
In 2001 Deborah Freile and Kelly Fuks looked at algae rhodoliths of the Early Oligocene Bridgeboro Limestone in Grady County, Georgia. In the course of their research, they observed and filed these comments about crustaceans in the Bridgeboro…
“Other constituent grains were observed but not quantified. There include the foraminifera Homotrema rubrum, crustacean parts, and medium to coarse grained shell hash. The associated fauna is a low diversity. It includes common occurrences of the echinoid Clypeaster cotteaui, the bivalve Chlamys, crustacean appendages and carapaces…”

In the above chart Freile and Fuks identify Malacostracan crustaceans, spiny lobster appendages, as “common within caves systems in the quarry, not visible on quarry walls.” (Chart Page 103).
Note; Malacostracan is large class of crustaceans which includes crabs, shrimps & lobsters. Freile & Fuk did not identify the “spiny lobster” beyond class.

Huddlestun, Marsalis, & Pickering 1974
In 1974 Paul Huddlestun, William Marsalis, & Sam Pickering compiled a field trip for Southeastern Section of the Geological Society of America (GSA). This was a joint venture with the Georgia Geologic Survey, which was abolished in 2006. This is the report Bishop and Whitmore cited.

A PDF of their report is available below. It would be worthwhile project to retrace, recreate, and renew this field trip for amateurs and professionals. It passes through some of the richest fossil hunting ground in Central Georgia.
Getting a copy of it wasn’t easy. The GSA did not have a copy to share. I have no contact info for William Marsalis. My dear friend Paul Huddlestun is still in good health but sadly his memory is not. Sam Pickering passed during the Covid outbreak. I attended his funeral.
However, a few years ago, when Paul started fearing for his memory, he reached out to me about what he should do with his collection of samples and literature. He sent me several publications from his personal library. He retained many more, including all of his hand-drawn geologic sections. Sections that are the foundation for much of his research.
These were drawn, sediment bed by sediment bed, by Mr. Paul as he personally measured, observed and described each in his notes. As an example, the 1974 measured section at Medusa (Cemex) is 175 feet tall and broken down into 23 distinct beds.
I reached out to several Georgia institutions with no luck to find a home for Mr. Paul’s collection. Dr. Roger Portell at the Florida Museum of Natural History came to the rescue. We met Roger earlier. This institution has the largest specimen and literature collection in the Southeast. I put Roger and Mr. Paul in touch with each other and soon Portell visited Mr. Paul in his New Mexico home, loaded up Mr. Paul’s material, and had it sent to Florida for permanent housing. Thanks Roger!
When I struck out on scoring a copy of the 1974 field trip report, Roger was able to come to the rescue again and provided the below copy.

Having the paper I encountered a problem, the occurrence reported by Bishop and Whitmore doesn’t appear in the 1974 text. The location references are there, Bench B of the Twiggs Clay is clearly marked on the geologic section (Page 2-18) of the Medusa Quarry (now Cemex). Bench B rests between Bed 13 & 14, both of which are described in the 1974 text (page 2-33), but there is no mention of burrows or crustaceans in either. Nor is there a mention in the general description of the Twiggs Clay (beginning on page 2-8).
This led to the assumption that the occurrence Bishop and Whitmore reported was a personal communication based on the field trip’s research. Either Bishop and Whitmore were on the field trip, or they discussed it later with Mr. Paul.
Looking at the Florida Museum of Natural History collection database, I see several crustaceans were collected from the Tivola Limestone by my friend Gale Bishop being held by the museum. But there are none listed as coming from the Twiggs Clay.
Updating the 1974 field trip becomes a more interesting project. Evidence would suggest that there might be burrows in the Twiggs Clay, it’d be worth looking for them. As a fine grained, silty clay there’s no reason I can think for why burrows wouldn’t be present.

I don't seem to have any from the Tivola anywhere. I have a few Callianassa claw pieces from the Ocala (Limestone) near Leesburg and Albany, so probably the same things are in the Tivola, but I never saw them.

So, as it turns out Georgia has a significant history in crustacean fossils spanning the Late Cretaceous to the Pleistocene.
It’ll be interesting to see if more specimens are reported.
