Crinoids
have an extremely long fossil record, beginning to the
Ordovician period
and lasting until the present time,
a 500,000,000 million year record!
The fossils here
are
the
fossilized column, or stem part of the animal. Crinoids are called "
sea lilies
" because of its flowering-like tentacles at the crown,and are exclusively a marine animal.
Though
resembling a plant it is a member of the
Phylum Echinodermata
. Crinoids look like plants because the body skeleton, or calyx, generally grown on the end of a stem
made of
button-like arms.
Crinoid stems
or separate stem discs are common
throughout most countries of the world,
and are found in many states within the
United States
. The fact that crinoid stems
and
individual disc sections are found throughout the United States is evidence that at one time
most of the land
area that now make up the United States was once
under seas
.
Some
crinoids live today, mainly in
deep parts
of the ocean, but they are not nearly so common as in the past.
Most crinoids had a
foot-like bottom
section called a
holdfast
or
root
that it used to anchor itself to the sea floor. Above this foot-like section was the stem that supports the
animals crown of arms
that waved with the ocean movement. At the center of this crown of arms is the
calyx
, which contains the vital organs of the animal. The calyx is small
when compared to the total mass of the crinoid, most of which is devoted to food collection.
The mouth and anus
are located on the upper surface of the body, and are
connected
by a simple
gut
. The arms at the crown are composed of an articulated series of
ossicles
that are used in suspension feeding and respiration. The gonads are also
located in the
arms;
fertilization
takes place in open sea water during
mass spawning.
While most crinoids were stalked animals, rising from the sea floor with their stems, there are a number of species that are
"free floating" crinoids
, not being anchored to the
sea
floor. Scientists believe that during the long span of time that crinoids have existed,
that there have been over 600 species.
