Summary:
Jacksonboro limestone is a stratum of limestone containing numerous casts of shells and occasionally a silicified specimen, on the whole not unlike Tampa limestone. This stone was formerly burned for lime. The section near the confluence of Brier Creek and Beaver Dam Creek shows 5 ft of ferruginous sand and over 12 ft of compact marly rock with fossils. At present the presumption is obviously in favor of an early Miocene age for this deposit.

Pg. 1573. Author has no reasonable doubt that the horizon of Jacksonboro white limestone is practically that of the Tampa limestone.
