It was a bit of a shame that the fossil-trackway site pictured on the cover of the June 9 issue was not identified, as it is one of the more remarkable ones ever uncovered in North America . The tracks shown are a few of hundreds across the floor of a quarry near Culpeper, Va. Almost all of the tracks were made by midsize theropods, which may have been cruising the shallows of a Triassic lake basin in search of prey. Researchers made detailed maps of the trackways in the late 1980s, and a few siltstone blocks were removed and exhibited at various other sites. James Bryant

Riverside, Calif. The dinosaur tracks are some of the thousands spread across the 6-acre floor of the quarry. Some are now on display at the U.S. Geological Survey headquarters in Reston, Va., the Virginia Museum of Natural History in Martinsville, and the Museum of Culpeper History. Others went to the Smithsonian Institution’s National Museum of Natural History. Most tracks not removed were lost to subsequent quarrying. The remainder lie beneath a small lake at the bottom of the quarry.–S. Perkins
