Dictyoconites from the middle Triassic Cassian Formation is a characteristic representative of the Aulacocerida. Embryonic development and construction of the phragmocone is like that of Jurassic belemnites. The siphuncular tube is double-walled with a long retrochoanitic mineralized septal neck continuing into an organic tube. The extended decoupling zone resembles that ofSpirula.

Aus dem eozänen Ölschiefer von Messel wird der erste Fund eines Primaten beschrieben. Es handelt sich um ein Teilskelett der hinteren Körperhälfte. Da Gebißreste fehlen, kann eine Bestimmung nur als Adapidae gen. et sp. indet. erfolgen. VonAdapis unterscheidet sich der Fund u. a. in den Proportionen des Calcaneus. Der Fuß zeigt die voile Spezialisierung zu einem Greiforgan mit abspreizbarem, verbr...... hiện toàn bộ
