A Paleontologist developed an equation to estimate the approximate total length of a crocodilian based on the diameter of its fossil coprolites. This was accomplished through the study of modern-day crocodilians and their excrement.
The equation for calculating crocodilian length based on coprolite diameter is as follows:
Crocodilian Length (cm) = [coprolite diameter (cm) - 1.10]/0.012
Using this equation, we can estimate that a coprolite with a diameter of 2 inches (5 centimeters) is likely to have been produced by a crocodilian that was 10.66 feet (3.25 meters) long.
A coprolite with a diameter of 5 inches (125 millimeters) is likely to have been produced by a crocodilian that was 31 feet (9.45 meters) long!
All specimens in this case are from South Carolina, USA. Age is Miocene. They are believed to be from crocodilians. 23 to 5 MYA.
