Figure 3 A. Sphecomyrma freyi Wilson and Brown from the lower part of Upper

Figure 3B. Paleomyrmex zherichini Rasnitsyn from the lower part of the Upper 
Cretaceous of U.S.S.R. Drawing of holotype male in Paleontological Institute, 
Moscow, from Rasnitsyn, 1977. Length of body, 5.4 mm. 
have been discovered. Mention is made by Brues (1936) of a piece of 
petrified wood containing what he considers ant borings, highly 
resemblant of borings made by Camponotus today. Although there 
is no clear-cut evidence that these borings represent Camponotus 
activity, or insect activity of any kind, it is conceivable that 
Camponotus was present in New Mexico during the Paleocene; 
several species have been dscribed from the Florissant Shales, 
Colorado (Upper Oligocene), and one from the Baltic Amber
