FUM-N-17627 (Coleoptera). ( Good ) Brand new traditional elytra inside dorsal consider just before testing, showing a weak metal be noticeable significantly less than conventional light. ( B ) High magnification of black amount in the town demarcated during the ( A great ). ( C ) SEM micrograph of your own exterior (outer) epidermis of the elytra. Notice hexagonal patterning and desiccation breaks. ( D , Age ) SEM micrographs of one’s smooth inner epidermis of your elytra. Notice hexagonally setup imprints about sedimentary matrix neighboring brand new fossil matter. ( F ) SEM micrograph proving a paragraph from the mainly amorphous cuticular matrix. Note thin layers along side exterior margin of elytra (expressed from the an enthusiastic arrow). ( Grams ) TEM micrograph depicting a vertical part through the elytra. Note mainly amorphous interior save your self to have thin subvertical rifts (white arrows) and you can four electron-heavy layers you to definitely solution that have slimmer, electron-transparent bands (black colored arrow). ( H ) Higher magnification of your narrow formations (light arrow) and epicuticular layering (black arrow). ( We ) TEM micrograph reflecting undulating, electron-lucent fibrillar nanostructures (arrows) on the otherwise mostly homogenous cuticular matrix. ( J , K ) Higher magnification of one’s structures illustrated in the ( We ) proving personal filaments. ( L – Letter ) SEM micrographs depicting stays regarding putative seta, sensilla otherwise microtrichia-including have. ( O ) SEM micrograph appearing the 2 mineral phase recognized directly in relationship towards elytra. The newest great texturing which have collection of polygonal imprints of calcium supplements-rich phase (white arrow) is actually distinguishable in the more rough-grained iron-steeped and you will silicon-rich phase (black arrow).
New spectrum regarding the yellow town demonstrates the brand new generation out-of https://hookupwebsites.org/the-inner-circle-review/ mixed group ions off silica and you will iron-oxide
SEM-EDX elemental charts extracted from brand new fossil beetle elytra (FUM-N-17627). C, carbon ( red ); California, calcium ( bluish ); Fe, metal ( orange ); Milligrams, magnesium ( cyan ); O, fresh air ( purple ); S, sulfur ( yellow ); Lorsque, silicone polymer ( green ).
( An excellent – D ) Negative ion photos representing ( A ) silica, ( B ) eumelanin and you will ( C ) natural sulfur, together with ( D ) a keen overlay picture in which silica was portrayed from inside the red, eumelanin into the green and you will all-natural sulfur in bluish. ( Elizabeth ) Negative ion spectra taken from chose ROIs you to definitely correspond to the brand new eco-friendly (eumelanin) and yellow (silica) parts for the ( D ), respectively, where in fact the spectrum in the eco-friendly town try matched against source spectra out of artificial and you will absolute eumelanin criteria. ( F – I ) Positive ion pictures symbolizing ( F ) the fresh new mixed silica/iron-oxide phase, ( G ) Ca-which has all-natural complexes and you will ( H ) calcite, and ( I ) an enthusiastic overlay picture where silica/iron-oxide try depicted from inside the yellow while the California-which includes organics is actually eco-friendly and you can calcite is within blue. ( J ) Self-confident ion spectra in the red, eco-friendly and you may bluish section during the ( We ). This new spectrum about bluish town is actually compared against a resource spectral range of calcite.
ToF-SIMS characterization away from fossil beetle elytra (FUM-N-17627)
FUM-N-11263 (Hymenoptera). ( An effective ) Optical microscopy image of the brand new fossil wasp with a dark thorax and lead, and you will red-tinted gut and foot displayed inside the lateral view. ( B ) Higher magnification photo indicating brown pterostigma (arrow), a-wing vein in addition to side facial skin that have abundant microtrichia (arrowheads). ( C ) SEM micrograph out of inferred cuticular fragments in the pterostigma and additionally damaged bristles (arrows). ( D ) Optical microscopy image of the newest thin section joining brand new thorax and you will gut, showing differences in preservation within dark-colored count and you will red-colored foot. ( E ) SEM micrograph of the town demarcated inside the ( D ) exhibiting inferred cuticular remains. ( F ) SEM micrograph of one’s ventral side of the instinct which have carbonaceous spots (arrows) allegedly representing relict cuticle.
