 Description:
Well-preserved example of a “conglomerate” composed of
delicate Echinoids (sea urchins) . The tests (shells) of urchins are
typically quite fragile, so not found intact too often. Most modern-day
examples are found broken in the surf. This group must have been filled
with sediment shortly after the death of the urchins, or burial may
have been the cause of death. Either way, this fine example has been
preserved intact for its nearly 100 million year journey into the
present. Both sides have an extensive collection visible, a most unusual
Echinoid that as yet has not been identified. Even more unusual, a
number of spines of the urchins have also been preserved, showing
burial had to be near the time of death. |
