This paper describes a new genus and species of weevils from Baltic amber (Eocene, 55–34 million years old). This fossil resin can be found throughout the Baltic Sea coastal area in northern Europe (Kaliningrad region, Russia; Poland; Denmark; Sweden; Germany; and Lithuania). The new fossil weevil is more similar to extant American genera, but its host plants cannot be assumed. The new fossil genus is named in honour of Carsten Gröhn (Germany), an enthusiast and specialist in Baltic amber.

We describe a bizarre and extinct caddisfly species, Cretapsyche palpinova sp. nov., from mid-Cretaceous Burmese amber.

The Jehol Biota of northeastern China (western Liaoning and conjoint areas) is renowned for its exquisite preservation of plant, invertebrate and vertebrate fossils. Here, we report three new specimens of the freshwater sinemydid turtle Ordosemys liaoxiensis from Hengtongshan Formation of Meihekou City, Jilin Province, northeastern China. As the first Mesozoic turtle of Jilin Province, this record represents the first tetrapod to indicate the presence of the Jehol Biota in the region.

The current paper describes a new fossil genus of spider beetles from Baltic amber (Eocene, 34–55 million years old). This fossil resin can be found throughout the Baltic Sea coastal area in northern Europe (Kaliningrad region, Russia; Poland; Denmark; Sweden; Germany; and Lithuania). The examined fossil material is housed in the private collection of Christel and Hans Werner Hoffeins (Hamburg, Germany).

In this paper we focus on an insect wing fragment from the rarely known Taiyuan Formation (Early Permian; China). It is the first discovery of an arthropod as well as being the first insect, but currently we think the combination characters that the new material exhibited make it difficult to assign it to any known insect group. This indicates that more data are needed in the future. Hopefully our current documentation will be useful for the potential fossil discovery in the Taiyuan Formation.

Here, we describe an enigmatic new microfossil that was found encrusting a belemnite from the Middle Jurassic of the Falaises des Vaches Noires in Normandy, France. The organism has produced a conspicuous attachment etching on the belemnite for better adhesion and this trace fossil is new to science as well. Based on morphological criteria and the capacity to bioerode, the new microproblematicum can best be compared to encrusting bryozoans and foraminiferans.

In this paper we describe a new fossil species of the silvanid flat bark beetle from Baltic amber. The new beetle species from European Eocene belongs to the genus living only in the New World now. Possible, the studied specimen is an adult beetle entrapped in resin shortly after moulting.

Only in recent years have new genera and species of the subfamily Silinae Mulsant, 1862 been described as inclusions in amber. However, no representative of the genus Silis Charpentier, 1825 had been described from Baltic amber, even if few specimens were already known at the generic level. Silis lombardii sp. nov. is entirely dark brown and shows (as usual for the genus) the two characteristic lobes in the sides of pronotum, elongated elytra, and a basal small tooth only on the anterior claws.
