Didymograptus murchisoni, Ordovician, GB-WLS
Specimen with well-preserved graptolite Didymograptus murchisoni (BECK).
Graptolites were colony-forming filter feeders that developed organic exoskeletons. Their imprints are typical for the Ordovician and Silurian. The first forms were sessile, the later types like this one floated in the water. They were long thought to be extinct until the deep-sea creatures Rhabdopleura were recognized as graptolites a few years ago.
