   Abstract : Trilobites were a successful group of marine arthropods that thrived for much of the Palaeozoic Era. Akey innovation of trilobites involved the capacity to enrol their biomineralized exoskeletons for protection; a trait that appeared early in their evolutionary history during the Cambrian Period.

   Keywords : biostratigraphy; Sweden; Västergötland; drill core; agnostoids; trilobites; δ13 excursion DICE ; Cambrian; carbon isotope stratigraphy; Earth and Environmental Sciences;

   Abstract : The Tomten-1 drilling at Torbjörntorp in Västergötland, southern Sweden, penetrated 29.85 m of Cambrian Series 2 and 3, Furongian, and Lower and Middle Ordovician strata. The biostratigraphy, sedimentology and carbon isotope (δ[sup]13[/sup]C[sub]org[/sub]) stratigraphy of the core have been analysed. READ MORE
