Sedimentary structures associated with the fossils include asymmetrical current ripples, raindrop imprints, desiccation cracks, and gas-escape structures.
Sedimentary structures such as raindrop imprints, gas-escape structures and desiccation cracks, common on other slabs, are absent from these slabs.
Both slabs preserve raindrop imprints and desiccation cracks.
An additional slab, SSM 2015/326, is similar to SSM 2015/3-23 in being shaly and preserving raindrop imprints, but the raindrop imprints are much larger on SSM 2015/3-26, having a diameter up to 10 mm.
OCCURRENCE: This trackway occurs on a small slab of grey shale that exhibits mudcracks and raindrop imprints. Additional invertebrate trace fossils in direct association with Mitchellichnus cf.

Sedimentary structures associated with these trackways include mudcracks and raindrop imprints. Associated invertebrate trace fossils include the insect trackways Mitchellichnus cf.
Other sedimentary structures indicative of subaerial exposure and associated with desiccation mudcracks include raindrop imprints, evaporite casts, vertebrate tracks, bubbles and foam impressions (Plummet & Gostin 1981).
The bedding plane surface contains raindrop imprints. This hand sample contained three sets of shrinkage cracks that were independently formed because their pattern did not match vertically (Fig.
No raindrop imprints were noted, but a bumpy irregular algal mat surface was obvious.
4) with raindrop imprints further support our interpretation of subaerial exposure and the desiccation process.
