His collection features samples from 15 states and eight other countries throughout the world.
The largest piece in Frandsen's collection weighs 4 pounds and 3.5 ounces. He's nicknamed it "Precious."
The Miocene epoch sample is between 23.8–5.3 million years old and was produced by a huge crocodilian species in South Carolina.
Frandsen's collection was documented at the South Florida Museum in Bradenton, Fla. and each piece was inspected to ensure its authenticity before he was given the record.
Frandsen said the samples are similar -- hard and rock-like in texture and do not smell -- but added anyone looking to rival his massive collection should be passionate.
"Have passion, lots of passion for whatever they're doing," he said. "Mine is coprolite – fossilized feces ...whatever your passion you should follow it."
