FUM-N-17627 (Coleoptera). ( A ) Brand new fossil elytra during the dorsal check just before testing, showing a faint steel excel lower than old-fashioned light. ( B ) High magnification of your own dark amount regarding town demarcated inside the ( Good ). ( C ) SEM micrograph of your own outside (outer) epidermis of your elytra. Mention hexagonal patterning and you will desiccation splits. ( D , Age ) SEM micrographs of simple interior body of the elytra. Mention hexagonally establish imprints about sedimentary matrix nearby the fresh fossil count. ( F ) SEM micrograph demonstrating a paragraph through the predominantly amorphous cuticular matrix. Mention narrow layers along the additional margin of your own elytra (conveyed by the an arrow). ( Grams ) TEM micrograph depicting a straight point through the elytra. Notice largely amorphous indoor save yourself to have slim subvertical rifts (white arrows) and you may five electron-heavy levels you to definitely choice that have leaner, electron-translucent groups (black colored arrow). ( H ) High magnification of your own narrow structures (white arrow) and you can epicuticular adding (black arrow). ( We ) TEM micrograph showing undulating, electron-lucent fibrillar nanostructures (arrows) throughout the otherwise mostly homogenous cuticular matrix. ( J , K ) Large magnification of your structures illustrated in the ( I ) proving personal filaments. ( L – N ) SEM micrographs portraying stays regarding putative seta, sensilla otherwise microtrichia-instance have. ( O ) SEM micrograph proving both mineral phases understood directly in connection for the elytra. The newest great texturing that have collection of polygonal imprints of your own calcium supplements-steeped stage (light arrow) is obviously distinguishable throughout the much more coarse-grained metal-steeped and silicone-rich phase (black colored arrow).
Brand new range on the reddish area demonstrates the newest age bracket regarding mixed people ions out-of silica and iron oxide
SEM-EDX essential charts extracted from the new fossil beetle elytra (FUM-N-17627). C, carbon ( red ); California, calcium supplements ( bluish ); Fe, iron ( lime ); Mg, magnesium ( cyan ); O, outdoors ( red ); S, sulfur ( red ); Quand, silicon ( green ).
( A good – D ) Bad ion pictures symbolizing ( An effective ) silica, ( B ) eumelanin and you will ( C ) natural sulfur, together with ( D ) a keen overlay photo where silica is illustrated within the red, eumelanin inside the green and all-natural sulfur in blue. ( Elizabeth ) Negative ion spectra taken from picked ROIs you to definitely match the newest eco-friendly (eumelanin) and red-colored (silica) components in ( D ), correspondingly, where in actuality the range in the green city are matched against site spectra out of artificial and you can sheer eumelanin criteria. ( F – We ) Confident ion photos symbolizing ( F ) the newest blended silica/iron oxide stage, ( Grams ) Ca-with natural buildings and you may ( H ) calcite, in addition to ( We ) an enthusiastic overlay picture where silica/iron-oxide try depicted inside reddish and the Ca-that contains organics is actually environmentally friendly and you may calcite is https://hookupwebsites.org/sugardaddymeet-review/ within bluish. ( J ) Confident ion spectra in the red, environmentally friendly and you can bluish parts inside ( I ). The fresh range on the blue city try compared to a resource spectrum of calcite.
ToF-SIMS characterization out of traditional beetle elytra (FUM-N-17627)
FUM-N-11263 (Hymenoptera). ( A beneficial ) Optical microscopy picture of the newest traditional wasp that have a dark colored thorax and you can direct, and you will reddish-shaded instinct and you will legs displayed for the horizontal glance at. ( B ) Highest magnification photo proving brown pterostigma (arrow), a-wing vein and also the side surface having numerous microtrichia (arrowheads). ( C ) SEM micrograph away from inferred cuticular fragments regarding the pterostigma also busted bristles (arrows). ( D ) Optical microscopy picture of the fresh new thin part signing up for the new thorax and you will instinct, showing differences in maintenance amongst the dark-coloured matter and you may red-coloured legs. ( E ) SEM micrograph of one’s city demarcated into the ( D ) exhibiting inferred cuticular remains. ( F ) SEM micrograph of your ventral area of the abdomen having carbonaceous places (arrows) allegedly symbolizing relict cuticle.
