This sample was taken from a low marshy pond worked by beavers, likely part of a former river channel. The shallows were crowded with water milfoil and other aquatic plants, providing shelter for many small animals including brook stickleback, giant pond snails, and various insects.
Different green algae, especially filaments and small desmids, were very common. There were also larger greenish to orangish globes of tapering Nostocales, found mainly on plants and often home to Ptygura. Rotifers in general were widespread, notably Lecane and lepadellids, as were vorticellids and especially Strobilidium.
