(Rich Fuchs collection) Graptolites are an extinct group of hemichordates that are most commonly preserved as carbonized compressions on shale bedding planes. They are typically not glamorous fossils, but they are critically important guide fossils and are widely used in biostratigraphy and for Part 1: learn the relevant fossil taxa.

Ordovician, Foreshore, Rating: ♦♦♦♦ I Sverige finns fossilrika graptolitskiffrar, vilket bland annat medfört att svenska forskare gjort pionjärinsatser inom framväxten av graptolitstrafigrafin. Koloniskelettens likheter med dem hos de nutida fjädermaskarna (Pterobranchia) har gjort att de båda djurklasserna numera räknas till samma djurstam – svalgsträngsdjuren.

Graptolites fossil record is of a global scale. They are exclusively found in marine sedimentary rocks of the upper Cambrian right through the Ordovician, Silurian and the Lower Carboniferous. They are commonly found in black, organic and iron sulphide rich mudstones and shales, the so called ‘graptolite facies’ (Jstor, 2014). Our interpretations are not entirely restricted to speculation any more, and it is now accepted that the graptolites represent a largely fossil group of the Pterobranchia (Maletz, 2014a (Maletz,, Graptolites (The class) include the order Dendroidea, a multi-stiped ancestral version of the graptoloids.
