Friday March 27 - 1931
Ocala, Florida.
Had the car of yesterday take me at 8:30, 6 miles south to the Ocala Lime Rock Corp., quarries, that I saw coming south from Gainesville. Started drilling into the first quarry, where they have gone down about 60 feet or more. Between 40'-50' beneath the roofing rim stained formation is the main zone of the layer foraminifera; here the echini are rarer and smaller, and the peclum and canusium not so common as they are higher up. Drilled here from 9 A.M. to 1:30 P.M.
Then came back over the Gainesville road to the old quarries and here is a shelf just on the level of the main echini bed. There I got in three hours about 60 echini and a great variety with many large species. Large foraminifera are common here but far and away not such great quantity long than down down. It is in the same that most of the flint occurs. These were made by circulating currents during the Oligocene when this part of Florida was land. This zone is about 20 beneath the top of the Ocala and is about 5 feet thick. Peclum are common, and have a large oyster.
Got about 100 echini today. If the day is good to me as usual try again with same quarries.
