Clown beetles (Histeridae) are insufficiently studied in fossil resins. The aim of the present research is to describe a new species of Bacaniini from Eocene Baltic amber. The specimen is studied using X-ray micro-computed tomography, imaged and compared with fossil and extant related beetles. A mixed sporophagous–predaceous diet in rotten wood of fallen and standing trees was assumed to be the ecological niche for the fossil species.

A male of the extinct leaf-beetle species Calomicrus eocenicus embedded in Baltic amber is found and compared with an earlier known female. The beetle genitalia are illustrated in detail using X-ray microtomography. The male is smaller than female and has a modified last abdominal segment. The extinct species (about 40 million years old) possesses typical sexual characters which are similar to the characters of extant beetles within the group.

We describe a new species and genus of weevils, Baltacalles triumurbium, from the Eocene amber of the Sambia Peninsula (Kaliningrad Region, Russia). The new fossil represents the first Eocene representative of the group. In addition to the taxonomic work, the locally distinct deposits of Baltic amber in the Kaliningrad Region are listed, discussed, photographed and mapped. The importance of the possible exact labeling of the amber material is underlined.

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.

The new weevil Igneonasus rudolphi gen. et sp. nov. of the tribe Ceutorhynchini is described from the late Oligocene of Fossillagerstätte Enspel, Germany. The new genus is similar to the Recent genus Stenocarus and the largest representative of the supertribe Ceutorhynchitae. It is the first fossil Curculionidae species described from the paleolake Enspel. In this ancient ecosystem, weevils were at least sometimes an important food resource for the cyprinid fish Palaeorutilus enspelensis.

New fungus weevils, Eduardoxenus unicus gen. et sp. nov. is described from late Eocene Rovno amber (Klesov, Rovno region). This fossil fungus weevil is the oldest finding of the tribe Valenfriesiini in fossil state and the first record of the Choraginae from the Eocene ambers. The new genus differs from the genera Cyptoxenus, Valenfriesia and Neoxenus. Palaeogeographical and palaeoclimatological importance of finding Valenfriesiini in Rovno amber is discussed.

The Chehrabad area, NW Iran, is known as the historical site of Saltmen mine dated to the Achaemenid and Sassanid eras. We, however, discovered animal footprints in NW Chehrabad (ca. 3 km NW of the Saltmen mine) on a very large slab. These footprints belong to the Miocene age and include canid, felid and bird tracks as old as 10.7 Ma. The canid footprint record establishes the late Miocene presence of canids on the Iranian Plateau as part of the Eurasia-wide “Eucyon event”.

Whereas true dolphins (Delphinidae) are the most diversified family of cetaceans today, their evolutionary history remains poorly known due to a relatively patchy fossil record. Based on a fossil skull discovered in early Pliocene (5 to 4.4 million years ago) marine sediments from Antwerp (Belgium), we describe here a new genus and species of small dolphin, Pliodelphis doelensis. This is the first delphinid species to be recorded from the early Pliocene in the North Sea.

Clown beetles (Histeridae) are insufficiently studied in fossil resins. The aim of the present research is to describe a new species of Bacaniini from Eocene Baltic amber. The specimen is studied using X-ray micro-computed tomography, imaged and compared with fossil and extant related beetles. A mixed sporophagous–predaceous diet in rotten wood of fallen and standing trees was assumed to be the ecological niche for the fossil species.

The 296 million year old rocks of Odernheim (Germany) preserve numerous fossils of fishes and amphibians (temnospondyls) of Permian age. This site is exceptional for yielding two large temnospondyl predators: the 2 m long Sclerocephalus nobilis and 1.5 m long Glanochthon lellbachae. A revision of G. lellbachae reveals that it forms the most ancient relative of the genus Glanochthon, a gracile fish eater, and that the origin of this group can be traced back to the genus Sclerocephalus.

Although thousands of vertebrate remains have been found in Thailand, few amphibian remains have been reported. Here, we present an overview on the Thai amphibian paleo-diversity. The Thai amphibian fossils show the most diverse Mesozoic amphibian record in Southeast Asia, and this agrees with the hypothesis of a large physical connection between the Indochina block and Laurussia during the Mesozoic era.

Biodiversity at the primate-bearing Çorakyerler site, Turkey, dating to the upper Miocene, is high, including up to 10 distinct bovid taxa. In this work, we describe five new bovid crania of a new bovid genus and species, Gangraia anatolica. The new taxon is characterized by long, keelless, and transversally ridged, homonymously twisted horn cores, and it shows a particular mixture of caprine and alcelaphine cranial features that are similar to the Alcelaphini–Caprini–Hippotragini clade.

Glaesotropis rohdendorfi sp. nov. belongs to the subgenus Electranthribus, described from Eocene Rovno amber. The new species is similar to G. zherikhini from Baltic amber. It is the first described beetle from the Olevsk amber locality, the sixth amber species reported from the Zhytomyr region, the first record of the subgenus Electranthribus, and the third Anthribidae from Rovno amber. An aggregation of glaesacarid mites as a syninclusion with the fungus weevil is reported for the first time.

The new weevil Igneonasus rudolphi gen. et sp. nov. of the tribe Ceutorhynchini is described from the late Oligocene of Fossillagerstätte Enspel, Germany. The new genus is similar to the Recent genus Stenocarus and the largest representative of the supertribe Ceutorhynchitae. It is the first fossil Curculionidae species described from the paleolake Enspel. In this ancient ecosystem, weevils were at least sometimes an important food resource for the cyprinid fish Palaeorutilus enspelensis.

Filter-feeding ctenochasmatid pterosaurs flourished in the Jehol Biota. Here, a new wing skeleton of the ctenochasmatid Forfexopterus is described from the Early Cretaceous Jiufotang Formation in Jianchang, western Liaoning, China. Interestingly, it exhibits a skeletal maturity with co-ossified elements, but it is only about 75 % the size of the immature holotype, revealing a developmental variation of Forfexopterus.

Forcipulatacea is one of the major clades of extant sea stars with 400 extant species described, but with fewer than 25 fossil species known. Thus, the identification of any new fossil representatives is significant. We reappraise Ophidiaster davidsoni from the Tithonian of Boulogne, France, which was assigned to another major extant group, and reassign it within a new forcipulatacean genus Psammaster gen. nov. A phylogenetic analysis does not place it within any existing forcipulatacean family.

Mennerotodus is a genus of fossil shark that lived during the Paleogene Period, between 65 and 38 million years ago, and was previously known only from Asia and Europe. In this study, new species of Mennerotodus have been identified in the USA from Alabama (Mennerotodus mackayi) and South Carolina (Mennerotodus parmleyi). Mennerotodus mackayi is the oldest of the species, suggesting the genus originated in the Gulf Coastal Plain of the USA during the Paleocene Epoch (~ 65 million years ago).

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 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.

Amber is fossilized resin and so has a terrestrial source; however, very rarely have marine microorganisms been reported, and only in a few amber pieces. We aim to understand how this rare phenomenon could be possible. Several different mechanisms were proposed, and we then tested the wind-blown idea via our experiments on resin-rich forests on the coast of New Caledonia. These forests encompass the best model for the Cretaceous ambers that contain these marine microorganisms.

Our ability to reconstruct the marine planktonic diatom early Paleogene history is hampered by decreased preservation as well as by observation bias. Collecting new diatom data in various Paleocene samples from legacy deep-sea sediment sections allows us to correct for the latter. The results show that the Paleocene deep-sea diatoms seem in fact as diverse and abundant as in the later Eocene while exhibiting very substantial survivorship of Cretaceous species up until the Eocene.

Selected specimens from the Jurassic ammonoid Pararnioceras sp. revealed striking changes in the conch morphology due to a syn vivo growth through a parasitic serpulid. Changes in its ontogenetic development are compared with specimens without epizoans.

We describe a biting trace on the oral surface of a large Maastrichtian holasteroid echinoid Echinocorys ovata from Hemmoor (northern Germany) which exhibits four circular punctures, arranged in a semi-circular arc. The punctures were not lethal to the sea urchin as is indicated by progressed skeletal regeneration and closure of the fractures. The shape and arrangement of the biting trace are analyzed suggesting that it was produced most likely by a globidensine mosasauroid.

The objective was to investigate inner ears and in particular the morphology of the cochlea of fossil and Recent baleen whales to reconstruct the occurrence of low-frequency hearing. Our results of cochlear shape analysis indicate that very low-frequency hearing appeared in the middle Miocene, and infrasonic hearing had evolved by the late Miocene. Cochlear coiling shape is suitable for estimating hearing limits in whales, closely approximated by cochlear length times number of cochlear turns.

A new fossil species relative of grasshoppers, crickets and katydids is described from the famous Xiaheyan locality (China). Compared to other species recovered from these 310-million-year-old strata, Sinogerarus pectinatus gen. and spec. nov. is likely most closely related to extant forms. The group it belongs to will become preeminent a few million years later but is very rare at Xiaheyan.

A partial carapace of a turtle from the middle Eocene of Saint-Gilles is presented here. Although it was donated to the Institut royal des Sciences naturelles de Belgique (Brussels, Belgium) more than a century ago, it remained undescribed. Its study allows us to recognize the second pleurodiran turtle in the Belgian fossil record. It is the first partial articulate shell of a pleurodiran recognized in Belgium, and the only member of this clade recognized in this country at specific level.

Short summary
DNA-based divergence time estimates suggested major changes in the composition of epiphyte lineages of liverworts during the Cretaceous; however, evidence from the fossil record is scarce. We present the first Cretaceous fossil of the liverwort genus Radula in ca. 100 Ma old Burmese amber. Our analyses support origins of most extant subgenera of Radula by the end of the Cretaceous and diversification of their crown groups in the Cenozoic.
