Early cephalopod evolution clarified through Bayesian phylogenetic inference
Background Despite the excellent fossil record of cephalopods, their early evolution is
poorly understood. Different, partly incompatible phylogenetic hypotheses have been …

Discontinuous, asymmetric and irregular colour patterns in Silurian oncocerids (Nautiloidea) with cyrtoconic shells.
V TUREK, Š MANDA - Bulletin of Geosciences, 2020 - search.ebscohost.com
The colour pattern is a conspicuous character of nautiloid shells. Better understanding to its
evolution and possible function is limited by the rarity of preservation. The majority of colour …
