These
traces may have been made by fish as they swam near the bottom
of the water. Or the trace may have been made by a fish after
it died.
During the Carboniferous Period, the fish found at Horton Bluff
had many spines -- it is possible that the spines made these
traces as a dead fish was washed back and forth in the waves.
Some scientists think these traces were made by dead plants
that were washed back and forth in the waves. What do you think
happened? |
