SUPPLEMENT TO STUDIES IN THE PLEISTOCENE AT 
VERO, FLORIDA 
E. H. SELLARDS 
After the papers in this volume, relating to the Pleistocene at 
Vero, Florida, were printed, but before they were distributed, three 
additional papers on this general subject appeared in the Journal of 
Geology. The papers referred to, which may be added to the bibli¬ 
ography given on page 69 of this report, include the following: 
Note on the Deposits Containing Human Remains and Artifacts at Vero, 
Florida, by E. H. Sellards, Journal of Geology, vol. 25, pp. 659-660, October- 
November, 1917. 
The Fossil Plants from Vero, Florida, by Edward W. Berry, Journal of 
Geology,.vol. 25, pp. 661-666, October-November, 1917. 
Further Studies at Vero, Florida, by Rollin T. Chamberlin, Journal of 
Geology, vol. 25, pp. 667-683, October-November, 1917. 
The paper by D<r. Berry is an abstract from the paper on fossil 
plants at Vero, which is published in full in the present volume 
(pp. 19-33). The brief note by the writer is also included in sub¬ 
stance in this report (pp. 69-82). The paper by Dr. Chamberlin 
contains an important modification of the hypothesis previously 
proposed by him, and in addition there is proposed a new hypothesis 
of the origin of certain of the fossils of the deposits. This contri¬ 
bution is based on observations made at Vero in March, 1917, at the 
time of Dr. Chamberlin’s second visit to the locality. 
It will be recalled that the essential features in which Dr. Cham¬ 
berlin’s former hypothesis differs from the. views held by the writer 
are that the extinct vertebrates of the stream bed are secondary and 
not primary, and hence are not diagnostic of the age of the beds in 
which they are found. The assumed source of the fossils is an 
older formation lying farther inland. In the present paper he 
abandons this hypothesis of fossils washed from farther inland, so 
far at least as it has any practical or immediate application to the 
problem in hand, and concedes that the fossils of the lower part of 
the stream bed are essentially if not altogether primary. On the
