Crinoids Fossils are also known as sea lilies, or
feather-stars and have been around for 450million years and some varieties are
still living today in our oceans in deep waters over 200 meters deep so you
will not see them when you go snorkelling.
It is a sea animal and not a plant as the name suggest, as
the animal had out reaches that look like branches and its base was a stem that
anchored to the sea floor. These stalks can be over meter long.
Crinoids had three distinct parts, the stem which anchored
to the floor is the strongest fossil shape to find, as skeletons are made of
calcareous plates. This is a very tough rock material, with some arms showing
in minor petalites as fossils are found in many European countries and Morocco
in North Africa.
Plant fossils are popular with fossil collectors as many
countries have excellent fern fossils specimens. Some go back over 2700 million
years ago. Many ferns and cycads are still around today and are living fossils.
Fire burns plants but some specimens do contain charcoal and
are well sought after by collectors. Wood or vegetation matter can be considered
plant fossil as permineralized fossil wood.
Peanut wood fossil from Australia is special as it was swept
into oceans before petrified and some contain borer holes making excellent
