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. Lees verder →
