PART B 4-6:
4) a) It appears to be a flexicalymene because of its hook shapes, there’s also
what appears to be chonetes. This would make the fossil below younger, and
the rocks overall relative age somewhere in the Devonian period.
b) Flexicalymene’s absolute age would be in the middle of the Ordovician
period and the Silurian periods. This is because chonetes appears right after
flexicalymene, and they appear in the same rock bed.
a) The relative age should be fairly old, as there’s phacops and mucrospirifer
embedded in the rock. This rocks relative age, however, is undeterminable, as
there are no other indications of which came first, since both fossils overlap in
