Charge Contrast Imaging of Exceptionally‐preserved Fossils

Abstract: Charge contrast images are a variant of secondary electron images acquired by operating a variable pressure scanning electron microscope in low vacuum mode; i.e. a gas is present in the specimen chamber. Spatial variation in the amount of charge that accumulates on the surface of the specimen is expressed as differences in greyscale tone; areas that are charging less are darker in tone. The precise mechanisms by which charge contrast images are generated are not known fully. Various different properties of a m… Show more

“…Results of combined SEM and EDS are consistent with previous studies showing that, like other fossils from the Solite Quarry Lagerstätte, the specimen is preserved as carbonaceous compressions with minimal topographic relief (Kearns and Orr, 2009; Muscente and Xiao, 2015). In general, the specimen was divided evenly between its part and counterpart during rock splitting (Fig.…”

“…Plant and insect fossils in the Solite Quarry Lagerstätte are preserved as carbonaceous compressions encrusted by silicate minerals, possibly biotite (Kearns and Orr, 2009; Muscente and Xiao, 2015). They appear silvery in color under reflected light microscopy, perhaps because of the presence of silicate minerals.…”

“…In some places, the carbonaceous material is encrusted by silicate minerals (Fig. 5F)-previously reported as biotite by Kearns and Orr (2009, fig. 3A) citing unpublished data-which appear brighter than the substrate in SSD(+) images.…”

“…Scanning electron microscopy (SEM) is a micro-to nanoscale characterization technique routinely used by paleontologists to collect high-magnification and high-resolution images for the study of fossil morphology and preservation (Taylor 1986;Orr et al 2002Orr et al , 2009Kearns and Orr 2009). SEM images are acquired through the detection of signal electrons emitted or reflected from a sample surface as it is raster scanned by a primary electron beam.…”

“…Burgess Shale fossils were examined using the complementary techniques of optodigital microscopy, environmental pressure backscatter electron microscopy, and secondary electron imaging (Orr et al . ; Kearns and Orr ), which together allow the observation of subtle compositional differences at a range of scales – and thus the recovery of high‐resolution anatomical detail and internal structure. HF acid‐isolated SCFs (see Butterfield and Harvey for processing techniques) were imaged using transmitted light microscopy.…”
