  We have discovered small, abundant, parallel-oriented, Rusophycus-like 
tracks in fluvial beds in the Late Triassic Chinle Formation in Dinosaur 
National Monument. Our suspicion is that they are made by an 
notosctracan crustacean. However, literature on supposed traces of these 
organisms seems limited. I have been trying to obtain a copy of the 
following paper, which reportedly describes such traces, but have had no 
luck, even through electronic subscriptions at several institutions. I 
was wondering if anyone on this list might have a pdf of it that they 
would be willing to send me:

Bromley, R.G. & Asgaard, U. 1979: Triassic freshwater ichnocoenoses from 
Carlsberg Fjord, East Greenland. Palaeogeography, Palaeoclimatology, 
Palaeoecology 28, 39–80.
