Horodyskia is a fossil
ised organism found in rocks dated from to . Its shape has been described as a "string of beads" connected by a very fine thread. It may also have had a series of holdfast
s along the bottom of the thread.
Comparisons of different fossils in the same locations suggest that it re-arranged itself into fewer but larger main masses as the sediment grew deeper round its base.
It may have been an early metazoan, or a colonial
