To the north of Catalonia at Besalú near Girona, there is a
limestone quarry with large mounds of mud that had once filled hollows (or
dolines) in the rock. In these mud mounds, prehistoric dung, snail shells and
sabre-tooth tiger bones were found. Normally the predator-prey ratio is 1:20,
but the sabre-tooth tiger bones found in the mud indicate a much larger ratio of
predator to prey. Some bones were very well preserved, but some were crushed or
had gnaw marks.
To make a long story short, how did all the bones get there?
Archaeologists have made up three theories, but which one is correct?
The Educational Comic Strip below illustrates the three
theories.
