"Diplograptus Multidens"?
Fossils from Abereiddi Bay / On a shale fragment .
A Graptolite fossil is not the remains of just an individual organism, but a colony of tiny
life forms called zooids / appearing in the early Ordovician period , extinct at the beginning
of the Silurian period / living in the sea, floating near the surface / feeding on microscopic
particles , which they were able to filter out of the water / each tiny "saw tooth" represents
the end of a tube , where a minute sea creature used to live / often called the 'Tuning Fork'
graptolite because of the overall forked appearance of the skeleton / the pointed end
at the top of the 'fork' would have been attached to some sort of float allowing the rest
of the skeleton to hang down in the water
