Florissant, Teller County, Colorado
Mr. Joseph Cancellare allowed me to photograph his large collection of insect fossils. We only had time to shoot a small part of his collection; which “consists of 2400 catalogued plants, insects, and fish fossils.” For more information about his collection and fossil location go to:
INVESTIGATION OF THE INTERMEDIATE SYSTEMATICS OF FOSSIL INSECTS COLLECTED AT THE CLARE QUARRY SITE IN THE FLORISSANT FOSSIL BEDS FROM 1996 – PRESENT
Estimated age is 34.07 +/- 0.10 million years old
This is an extinct species known only from the fossil record
