“…Walker and Behrens Yamada 1993). Mistaken predation on ammonites with secondary decapod crustacean dwellers has recently been suggested (Zinsmeister et al 1989), and is supported by the ®ndings described herein. Determining the presence and frequency of`hermitted' shells should now be a priority in studies of Cretaceous ammonite assemblages.…”

“…Comparisons of fossil and recent taxa show, that most taxa of the Brachyura (with the exception of the Carcineretidae, Retrorsichelidae, and Dakoticancridae, at both family and generic level, remained unaffected by the event at the K/T-boundary (Zinsmeister et al, 1989;Feldmann et al, 1995;Schweitzer & Feldmann, 2005). Collins & Jakobsen (1994) documented that approx.…”

In this article, I map the currently known brachyuran fossil record on a recent cladogram of Brachyura, the true crabs. The hypothesis of brachyuran phylogenetic relationships is based on a cladistic analysis of brachyuran foregut characters. With this approach, the following scenario of the evolution of Brachyura is proposed. The representatives of Brachyura that occur earliest in the fossil record (Dromioidea) take the most basal position in the cladogram, followed by Homolidae. These taxa reach their highest species diversity during the Cretaceous, together with Raninidae and Cymonomidae sensu lato. The analysis reveals that the majority of the "higher" crabs (Xanthoidea, Portunidae, Cancridae, and Oxystomata sensu lato) as well as their common ancestor existed already by the end of the Cretaceous. In particular, a constant increase of brachyuran species diversity has been registered from the Eocene to the Miocene. Most taxa of the Brachyura (with the exception of the Carcineretidae) remained unaffected by the events at the Cretaceous-Tertiary-boundary. Hence, the data suggest the events at the K/T-boundary have had a weaker influence on the species diversity of the Brachyura and of the Decapoda in general, than originally presumed: i.e., there was no massextinction of crabs. ZUSAMMENFASSUNGDie vorgestellte Hypothese, resultierend aus der kladistischen Analyse von Merkmalen der Vorderdarm-Morphologie, wurde mit dem gegenwärtig bekannten Fossilbericht verglichen. Basierend auf diesem Ansatz wird folgendes evolutives Szenario für die Stammesgeschichte der Brachyura vorgeschlagen. Die Vertreter der Brachyura mit den frühesten bekannten fossilen Vorkommen (Dromioidea) nehmen auch in der kladistischen Analyse die basale Position ein, gefolgt von den Homolidae. Diese Taxa zeigen zusammen mit den Raninidae und den Cymonomidae ihre größte Artenvielfalt während der Kreidezeit. Es ist ebenfalls anzunehmen, daß die Mehrheit der "höheren Krabben" (Vertreter der Xanthoidea, Portunidae, der Cancridae und der Oxystomata) ebenso ihr gemeinsamer Vorfahre schon am Ende der Kreidezeit existierten.

Innerhalb der neu vorgeschlagenen Neobrachyura sind neben den traditionellen Thoracotremata zusätzliche Taxa mit kontrovers diskutierten phylogenetischen Verwandschaftsbeziehungen zusammengefaßt. Für die ursprünglich beschriebenen Thoracotremata (Ocypodidae, Mictyridae, Gecarcinidae und Grapsidae) kann basierend auf Merkmalen der Gonoporen in beiden Geschlechtern von einem monophyletischen Ursprung ausgegangen werden. Nach Vorlage der verfügbaren Daten wird ein Event an der Kreide-Tertiärgrenze angenommen, welches einen kleineren Einfluß auf die Artenvielfalt der Brachy...
