Description:
A well-inflated example of a high-eyestalked member of the Asaphidae,
this is
Asaphus punctatus. The genus
Asaphus underwent some remarkable adaptations to changes in turbidity during
the Ordovician, with this one presumably arising in a time of increased turbidity. These
adjustments were thought to be able to allow them to see both predator and prey
more easily. The taxon
has variable eyestalk height, with this one having higher extensions than is
average.
