HBDLICKA] DISCOVERIES ATTRIBUTED TO EARLY MAN 33 
Plants : 
Plant remains in stratum No. 2 of the section at Vero are not numerous. 
In this respect this horizon differs from the alluvial bed which follows, in which 
is found an abundance of plant stems, seeds, and at places well-preserved 
leaves. The only recognizable plants obtained from this horizon are acorn 
cups, although in places are found stems and pieces of wood. The plant stems 
upon exposure to the air shrivel up ; the wood also has a tendency to fall to 
pieces upon drying. 
[P. 147.] Acorn cups, acorns, and other seeds are numerous, as are stems and 
pieces of limbs ; in places also where the conditions are favorable leaves are 
well preserved. The plant remains indicate a diversified flora representing a 
hammock type of vegetation, the term &quot; hammock &quot; being used in Florida to 
apply to a mixed timber growth, which usually includes a number of deciduous 
species. This type of vegetation occupies limited areas and contrasts with the 
pine lands, which are extensive. 
Invertebrates : 
[P. 143.] Fresh-water invertebrates are abundant in stratum No. 2 of the 
section and have been collected from several places in the bank. 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 number of marine 
species represented chiefly by young or small shells which were probably acci 
dentally included at the time the deposits accumulated. From the marl rock 
near the top of the stratum was obtained a single specimen of Ostrca, which, 
however, was probably introduced into the formation either by man or in some 
accidental manner. 
Vertebrates : 
[P. 144.] 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 deposits, the skeletons are for the most part disassociated. 
While all classes of vertebrates are represented, the mammals are by far the 
most abundant. 
Many families are represented, some by extinct, others by living 
species ; but the mammals are the most numerous. They include :
