Judging from those studied farther east, all of the shales in the 
above section are below the base of the Cleveland, with the pos- 
sible exception of the black shale of zone No. 13. 
Mr. Charles Maddock, who lives just west of the Lake Breeze 
House and formerly collected specimens of fossil fish with the late 
Mr. Jay Terrell at this locality, said that most of the specimens 
came from the black shale below the thin sandstone layer of zone 
No.g. This indicates that those specimens reported by Mr. Terrell 
from the lake shore near the Lake Breeze House came from the 
upper part of the Huron shale which farther east is equivalent, 
stratigraphically, to the upper part of the Chagrin formation. 
Dr. Newberry at first referred these fish-bearing shales to the 
Huron and stated that: 
the most interesting specimens found in this locality have rewarded the 
laborious and intelligent search of Mr. J. Terrell, the proprietor of the Lake 
Breeze House, situated in the immediate vicinity of the outcrop of the fish- 
bearing stratum.' .... These specimens we owe to the enthusiasm and 
intelligence of Mr. Jay Terrell, who found them at his home in Sheffield, 
Lorain Co. Here the upper portion of the Huron shale forms, along the 
Lake Shore, cliffs, which are being constantly worn away by the waves. These 
cliffs have been Mr. Terrell’s favorite hunting ground, and as the erosion of 
the surface revealed here and there the projecting point of a bone, each indi- 
cation has been followed up with care, and the bone taken out.2.... The 
large number of specimens since obtained, and, indeed, all the remains of 
Dinichthys hitherto taken from the summit of the Huron shale at Sheffield, 
belong, as we now know, to this species [D. terre/li], which is quite distinct 
from that found at the base of the formation at Delaware [D. herzeri].3
