“…Deeper examination of Amplectister internal characters through micro-CT scanning (e.g. Perreau and Tafforeau 2011, Riedel et al 2012) would be particularly informative, as some Saprininae apomorphies are found in the genitalia (Lackner 2014). …”

We describe a new genus and species of Histeridae from Upper Cretaceous Burmese amber, Amplectister tenax Caterino & Maddison, gen. & sp. n. This species represents the third known Cretaceous histerid, which, like the others, is highly distinct and cannot easily be placed to subfamily. It exhibits prosternal characters in common with Saprininae, but other characters appear inconsistent with this possibility. The abdominal venter is strongly concave, and the hind legs are enlarged and modified for grasping. We hypothesize that this represents the earliest example in Histeridae of modifications for phoresy on social insects.

“…The potential of µCT has been demonstrated before, but in taxonomic practice circumstances differ from unique experiments designed to show the capabilities of this technique (Lak et al ., 2008; Perreau & Tafforeau, 2011). The examination of holotypes of previously described species is especially difficult.…”

“…Inclusions in amber are usually devoid of compression artefacts and allow examination of fine details, but often the amber is not clear, the view is obscured by bubbles or cracks, and the specimen may only be observed from one aspect. Synchrotron microtomography (µCT) is a relatively new technique to overcome some of these limitations (Lak et al ., 2008; Dunlop et al ., 2011; Perreau & Tafforeau, 2011). It is here used to study features in specimens of relatively poor preservation, in particular the holotype of Sayrevilleus grimaldii Gratshev & Zherikhin, a species so far only known from this single inclusion in New Jersey amber.…”

Two genera of extinct weevils, Sayrevilleus Gratshev & Zherikhin from Cretaceous New Jersey amber and Baltocar Kuschel from Eocene Baltic amber, are recognized as close relatives based on similarities revealed by the use of synchrotron tomography and the availability of new amber inclusions. The subfamily Sayrevilleinae Legalov stat. nov. is characterized by possessing mandibles with an external cutting edge and an inner blunt edge. The subfamily is placed in the family Attelabidae (s.l.), although some characters also suggest a possible relationship with the ‘higher weevils’ comprising Caridae, Brentidae, and Curculionidae. Sayrevilleus is transferred from the tribe Auletini of Rhynchitinae to Sayrevilleinae, and Sayrevilleus grimaldii Gratshev & Zherikhin is redescribed. Baltocar Kuschel is transferred from Caridae to Sayrevilleinae and revised, its type species, Baltocar succinicus (Voss), is redescribed and three new species, Baltocar groehni Riedel sp. nov., Baltocar hoffeinsorum Riedel sp. nov., and Baltocar subnudus Riedel sp. nov. are described based on eight well‐preserved inclusions. The genera Orapauletes Legalov and Zherichiniletes Legalov previously assigned to Sayrevilleini are regarded as Curculionoidea incertae sedis. The Sayrevilleinae were distributed over areas of North America and Europe at least since the Late Cretaceous (c. 90 Mya) and were probably relatively diverse until the Eocene (c. 44 Mya). It is speculated that they became extinct through competition with Curculionidae, which used a similar oviposition strategy. © 2012 The Linnean Society of London, Zoological Journal of the Linnean Society, 2012, 165, 773–794.

“…Donoghue et al (2006) investigate fossilized embryos, whereas Tafforeau et al(2006) cover a wide range of fossils. More recently, Gai et al (2011) characterized a fossil of a jawless fish using synchrotron-based micro-CT. Other types of fossils include animals which have been preserved in amber , such as spiders (Bosselaers et al, 2010;Penney et al, 2007), beetles (Perreau and Tafforeau, 2011), pseudoscorpions ( Figure 9, which shows in high detail the right chelal fingers of the Pseudogarypus synchrotron Henderickx et al, 2012 at a reconstructed voxel size of 0.667³ µm³) (Henderickx et al, 2006;Henderickx et al, 2012) and earwigs (Perrichot et al, 2011). Other than these natural artefacts, man-made prehistoric objects are the subject of the research of Abel et al (2011).…”

Although the possibilities of X-ray micro-CT are becoming better appreciated in earth science research, the demands on this technique are also approaching certain physical limitations. As such, there remains a lot of research to be done in order to solve all the technical problems that occur when higher demands are put on the technique. In this paper, a review of the principle, the advantages and limitations of X-ray CT itself are presented, together with an overview of some current applications of micro-CT in geosciences. One of the main advantages of this technique is the fact that it is a non-destructive characterization technique which allows 4D monitoring of internal structural changes at resolutions down to a few hundred nanometers. Limitations of this technique are the operator dependency for the 3D image analysis from the reconstructed data, the discretations effects and possible imaging artefacts. Driven by the technological and computational progress, the technique is continuously growing as an analysis tool in geosciences and is becoming one of the standard techniques, as is shown by the large and still increasing number of publications in this research area. It is foreseen that this number will continue to rise, and micro-CT will become an indispensable technique in the field of geosciences.
