Pseudastacus is an extinct genus of decapod crustaceans that lived during the Jurassic period in Europe, and possibly the Cretaceous period in Lebanon. Reaching up to 6 cm (2.4 in) in total length, Pseudastacus had a crayfish-like build, with long antennae, a triangular rostrum and a frontmost pair of appendages enlarged into pincers, with those of females being more elongated. There is evidence of possible gregarious behavior in P. lemovices in the form of multiple individuals preserved alongside each other, possibly killed in a mass mortality event. With the oldest known record dating to the Sinemurian age of the Early Jurassic, and possible species surviving into the Cenomanian stage of the Late Cretaceous, Pseudastacus has a long temporal range and was a widespread taxon. Fossils of this animal were first found in the Solnhofen Limestone of Germany, but have also been recorded from France, England and Lebanon. All species in this genus lived in marine habitats.

The raspberry is the edible fruit of a multitude of plant species in the genus Rubus of the rose family, most of which are in the subgenus Idaeobatus. The name also applies to the plant itself. Raspberry plants are perennial with woody stems. It is an aggregate fruit, developing from the numerous distinct carpels of a single flower. Originally occurring in East Asia, the raspberry is now cultivated across northern Europe and North America and is eaten in a variety of ways including as a whole fruit and in preserves, cakes, ice cream and liqueurs. Raspberries are a rich source of vitamin C, manganese, and dietary fiber. Photograph credit: Ivar Leidus
