FOSSIL HUMAN REMAINS AT VERO, FLORIDA q 



water marl which, in places, reaches a thickness of 18 inches. The 

 maximum thickness of this stratum is about 5 feet, although its 

 average thickness is from 2 to 3 feet. 



The accompanying sketch, Fig 2, shows the section exposed 

 in the north bank of the canal from the railroad bridge west for 

 a distance of 500 feet. No. 1 is the marine shell marl; No. 2 is the 

 sand stratum which at the base is cross-bedded and at the top 

 passes into fresh-water marl; No. 3 is the deposit of muck and 

 vegetable material with alternating layers of incoherent sand. 

 The letter b indicates the location of one of the holes or channels 

 in the shell marl containing muck and driftwood as well as verte- 

 brate, invertebrate, and plant fossils. 



In Fig. 3 is shown a section, drawn to scale, of 75 feet of the 

 south bank of the canal, showing the exposure as seen in November, 

 19 16. This section includes that part of the bank west of the 

 entrance of the lateral canal from the south, and thus passes 

 through the exposure at which some of the important fossils have 

 been found. Stratum No. 1 has an approximately even top sur- 

 face, although at one place near the middle of the section it is cut 

 into rather deeply by stratum No. 2. This place, in fact, repre- 

 sents another of the holes or channels in No. 1 filled with muck 

 and decayed wood. Stratum No. 2 is variable in thickness, being 

 cut into at places by stratum No. 3. Stratum No. 3 as seen in this 

 section is variable both in thickness and in lithologic character- 

 istics. Its maximum thickness near the middle of the section is 

 about 5 feet, the upper 18 inches of which is a fresh-water marl. 

 The top or ground surface of this stratum is cut into at a and at b. 

 The cut at a was probably made in connection with dredging 

 operations. That at b, however, is evidently the channel of the 

 modern stream where it cut into stratum No. 3. 



At the point / in this section the muck and alluvial material of 

 No. 3 grades laterally by an indefinite line into the marl rock. In 

 the writer's former papers the whole section at e was referred to 

 stratum No. 2, No. 3 being interpreted as absent at this place. 

 The present exposure apparently indicates that the two feet of 

 marl at e is the equivalent of the muck and marl bed of No. 3. 

 A similar section is seen on the opposite or east side of the lateral
