CRETACEOUS INSECTS FROM LABRADOR 
1. GEOLOGIC OCCURRENCE 
By Erling Dorf 
Princeton University 
During the summer of 1958 a collection of fossil leaves and in- 
sects was made by the writer from a bed of ferruginous, red argillite 
associated with so-called rubble ore at the Redmond No. 1 deposit 
in the Knob Lake district of Labrador. This area is close to the 
Quebec border about 320 miles north of the town of Sept lies, 
which lies along the north shore of the St. Lawrence River. The 
fossil locality is 10 miles south-southeast of Schefferville, roughly 
half way between Knob Lake and Astray Lake (in section 260, ap- 
proximately 600 feet southwest of the 1957 Redmond No. 1 base 
line) . 
Fossil leaves were first discovered in this bed by Mr. Donald J. 
McMahon, geologist of the Development Division, Iron Ore Com- 
pany of Canada, during the course of trenching operations. A small 
collection of the leaves was sent to the writer for identifications and 
age determinations by Mr. Roger Blais, then Development Super- 
visor of the Iron Ore Company of Canada. Subsequently, Mr. Blais 
arranged for the writer to visit the locality in September 1958. 
During this visit the insect remains here described were discovered, 
in addition to the remains of 36 species of plants, including 1 alga, 
4 ferns, 1 lycopod, 3 conifers, and 27 angiosperms (Dorf, 1959). 
The field work and subsequent investigation have been jointly 
sponsored by the Iron Ore Company of Canada and Princeton Uni- 
versity. 
The 5-foot argillite bed in which the leaves and insects were found 
lies in the uppermost portion of the Redmond formation, a massive 
300 foot unit of rubble ore containing lenses of pale reddish to gray- 
ish clay. The argillite bed dips 45 degrees toward the east a*nd has
