SEM-EDX elemental maps extracted from ( Good ) wing blood vessels in the wasp, FUM-N-11263, and you will ( B ) thorax of one’s damselfly, FUM-N-10904. C, carbon (red); California, calcium supplements (blue); Fe, iron (orange); Milligrams, magnesium (cyan); O, outdoors (purple); S, sulfur (yellow); Si, silicon (green).
( planetromeo mumbai An effective – D ) Negative ion photos symbolizing ( A ) silica, ( B ) eumelanin and ( C ) iron oxide/sulfate, as well as ( D ) a keen overlay image in which silica is demonstrated inside red-colored, eumelanin for the eco-friendly and you will iron oxide/sulfate during the blue. ( E ) Negative ion spectra away from ROIs representing components with a high rule power out of sediment-related ions (red; top) and eumelanin-related ions (green; bottom), correspondingly.
Conceptual
FUM-N-17627 (Coleoptera). ( A ) The latest traditional elytra when you look at the dorsal evaluate just before sampling, exhibiting a light steel get noticed less than conventional light. ( B ) Higher magnification of your own ebony matter regarding town demarcated when you look at the ( An effective ). ( C ) SEM micrograph of your own additional (outer) facial skin of the elytra. Note hexagonal patterning and you can desiccation splits. ( D , Elizabeth ) SEM micrographs of your easy interior body of your elytra. Note hexagonally set-up imprints from the sedimentary matrix nearby the fossil number. ( F ) SEM micrograph exhibiting a paragraph from mostly amorphous cuticular matrix. Notice narrow levels across the outside margin of the elytra (conveyed by the an arrow). ( Grams ) TEM micrograph portraying a straight section through the elytra. Notice mainly amorphous indoor save for thin subvertical rifts (white arrows) and you will four electron-thick layers one to approach with thinner, electron-clear groups (black colored arrow). ( H ) High magnification of slim formations (white arrow) and epicuticular layering (black colored arrow). ( I ) TEM micrograph showing undulating, electron-lucent fibrillar nanostructures (arrows) on or even mostly homogenous cuticular matrix. ( J , K ) Large magnification of your formations represented inside the ( I ) exhibiting private filaments. ( L – N ) SEM micrographs portraying stays from putative seta, sensilla otherwise microtrichia-for example keeps. ( O ) SEM micrograph demonstrating the two nutrient stages understood in direct relationship on the elytra. The latest good texturing which have line of polygonal imprints of calcium supplements-steeped stage (light arrow) is truly distinguishable regarding a great deal more coarse-grained metal-steeped and you can silicone polymer-steeped stage (black colored arrow).
Simple Bottom line
SEM-EDX essential maps obtained from the newest fossil beetle elytra (FUM-N-17627). C, carbon ( red ); California, calcium ( blue ); Fe, metal ( tangerine ); Milligrams, magnesium ( cyan ); O, outdoors ( purple ); S, sulfur ( red ); Si, silicone ( green ).
ToF-SIMS characterization out of traditional beetle elytra (FUM-N-17627). ( Good – D ) Bad ion images representing ( An effective ) silica, ( B ) eumelanin and ( C ) organic sulfur, and additionally ( D ) an overlay image where silica are depicted inside red-colored, eumelanin for the environmentally friendly and you will organic sulfur during the blue. ( E ) Bad ion spectra extracted from selected ROIs that match the fresh environmentally friendly (eumelanin) and you can purple (silica) section inside ( D ), correspondingly, in which the range about eco-friendly town try compared to site spectra off synthetic and you may pure eumelanin standards. Brand new spectrum regarding reddish urban area reveals the latest age bracket away from blended cluster ions out-of silica and iron-oxide. ( F – I ) Positive ion images symbolizing ( F ) new blended silica/iron oxide phase, ( Grams ) Ca-that features organic complexes and you can ( H ) calcite, also ( We ) an enthusiastic overlay photo where silica/iron oxide is actually illustrated inside the purple in addition to Ca-with which has organics are environmentally friendly and calcite is within blue. ( J ) Self-confident ion spectra regarding the red-colored, green and you can bluish elements into the ( We ). The latest range regarding the bluish area are compared against a research spectral range of calcite.
