144 FLORIDA GEOLOGICAL SURVEY-EIGHTH ANNUAL REPORT. 
The species present are given in the accompanying list. These 
have been identified by Dr. Paul Bartsch, who states that all of the 
species are represented in the recent fauna. This is in marked 
contrast to the vertebrates among which are many extinct species. 
With the land and fresh-water invertebrates are found a num¬ 
ber of marine species represented chiefly by young or small shells 
which were probably accidentally included at the time the deposits 
accumulated. From the marl rock near the top of the stratum was 
obtained a single specimen of Ostrea, which, however, was prob¬ 
ably introduced into the formation either by man or in some acci¬ 
dental manner.

THE VERTEBRATE FAUNA. 
The vertebrate fauna from Vero is obtained from the fresh¬ 
water stratum, No. 2, and from the fluviatile deposit No. 3, none 
of the material so far as definitely known having been derived 
from the underlying marine marl. The vertebrate fossils occur in 
considerable numbers, although as is usually true of stream depos¬ 
its, the skeletons are for the most part disassociated. While all 
classes of vertebrates are represented the mammals are by far the 
most abundant. 
FISHES. 
Fish bones and teeth are found in this stratum in some abund¬ 
ance although in a fragmentary condition. Sharks are represented 
by isolated teeth, while vertebrae of fish are numerous.
