Als im Juli Flammen das Ladenlokal von Vivi Nuognava in der Bäckerstraße zerstörten, verlor sie innerhalb weniger Minuten die Grundlage ihrer Selbstständigkeit. Doch schon kurz nach dem Brand erlebte sie große Hilfsbereitschaft.

Abstract As actively swimming predators, cephalopods have played a key role regulating and engineering marine ecosystems for more than 500 million years and continue to do so. For the first time, we portray fluctuations of cephalopod body size including species from the Cambrian to today. For comparability, we determined the maximum body volumes of each species using various proxies, because classical measures like mantle length cannot be applied homologously to all groups.

Abstract Reproductive strategies of extinct organisms can only be recognised indirectly and hence, they are exceedingly rarely reported and tend to be speculative. Here, we present a mass-occurrence with common preservation of pairs of late Givetian (Middle Devonian) oncocerid cephalopods from Hamar Laghdad in the Tafilalt (eastern Anti-Atlas, Morocco).
