Estimated Age: about 450 million years old.
Comments: Scale Bar is 0.5 mm. About 50 times more conodonts
were recovered from this soft amorphous vein than were found in the hard
crystalized limestone surrounding it. This was the largest of about
250 elements recovered in this sample. Pictures M04 and M05 were
taken under oil immersion. Notice that unlike most blades, this element
is slightly bowed.
