FUM-N-17627 (Coleoptera). ( A ) The new traditional elytra into the dorsal have a look at before testing, exhibiting a faint steel be noticed less than traditional light. ( B ) High magnification of one’s ebony amount throughout the city demarcated within the ( A beneficial ). ( C ) SEM micrograph of the exterior (outer) surface of one’s elytra. Mention hexagonal patterning and you will desiccation splits. ( D , Elizabeth ) SEM micrographs of one’s smooth internal facial skin of your own elytra. Notice hexagonally set up imprints throughout the sedimentary matrix surrounding new fossil count. ( F ) SEM micrograph proving a part from the mainly amorphous cuticular matrix. Note thin levels along side outside margin of the elytra (conveyed because of the an arrow). ( Grams ) TEM micrograph portraying a vertical area from the elytra. Notice mostly amorphous interior cut having slim subvertical rifts (light arrows) and you may five electron-dense layers you to approach that have thinner, electron-transparent groups (black colored arrow). ( H ) Large magnification of your own narrow formations (light arrow) and you may epicuticular layering (black colored arrow). ( I ) TEM micrograph showing undulating, electron-lucent fibrillar nanostructures (arrows) about if not largely homogenous cuticular matrix. ( J , K ) Highest magnification of one’s structures depicted for the ( I ) appearing private filaments. ( L – N ) SEM micrographs portraying remains away from putative seta, sensilla or microtrichia-instance features. ( O ) SEM micrograph showing both mineral stages identified directly in connection into elytra. The good texturing having type of polygonal imprints of your own calcium supplements-steeped stage (light arrow) is actually distinguishable regarding even more rough-grained iron-rich and www.hookupwebsites.org/telegraph-review/ you may silicone polymer-rich stage (black arrow).
The new range throughout the reddish urban area reveals the fresh new age group regarding combined party ions from silica and you will iron-oxide
SEM-EDX essential maps obtained from brand new traditional beetle elytra (FUM-N-17627). C, carbon ( purple ); Ca, calcium supplements ( blue ); Fe, metal ( orange ); Milligrams, magnesium ( cyan ); O, outdoors ( purple ); S, sulfur ( purple ); Au moment ou, silicone ( green ).
( A great – D ) Negative ion pictures symbolizing ( Good ) silica, ( B ) eumelanin and you will ( C ) all-natural sulfur, in addition to ( D ) an overlay picture in which silica are portrayed in the red, eumelanin inside eco-friendly and organic sulfur when you look at the bluish. ( Elizabeth ) Bad ion spectra obtained from chosen ROIs one to match the newest green (eumelanin) and red (silica) components inside ( D ), respectively, where the range regarding green urban area try compared against site spectra out-of synthetic and you will absolute eumelanin requirements. ( F – I ) Positive ion photo symbolizing ( F ) new blended silica/iron oxide phase, ( Grams ) Ca-with organic complexes and you can ( H ) calcite, and additionally ( We ) a keen overlay picture where silica/iron oxide is actually depicted in the red in addition to Ca-that has had organics is actually green and you can calcite is during bluish. ( J ) Confident ion spectra throughout the yellow, environmentally friendly and blue parts during the ( We ). The newest range from the bluish urban area is actually compared against a research spectral range of calcite.
ToF-SIMS characterization of traditional beetle elytra (FUM-N-17627)
FUM-N-11263 (Hymenoptera). ( A ) Optical microscopy picture of the fresh new fossil wasp that have a dark thorax and you can lead, and reddish-shaded gut and you can foot exhibited inside the lateral view. ( B ) Highest magnification photo exhibiting brown pterostigma (arrow), a wing vein together with wing epidermis with numerous microtrichia (arrowheads). ( C ) SEM micrograph of inferred cuticular fragments in the pterostigma including broken bristles (arrows). ( D ) Optical microscopy image of this new narrow section joining new thorax and you will instinct, displaying differences in maintenance amongst the dark-colored count and red-colored-coloured base. ( Elizabeth ) SEM micrograph of your town demarcated when you look at the ( D ) proving inferred cuticular remains. ( F ) SEM micrograph of the ventral section of the instinct with carbonaceous places (arrows) presumably symbolizing relict cuticle.
