| Description |
English: Modern raindrop imprints in the Leucite Hills of Wyoming, USA (13 July 2015).
Raindrop imprints are scarce, but highly diagnostic, sedimentary structures. They absolutely demonstrate that a particular bedding plane was subaerially exposed - it had to be land. Raindrop imprints are expected to be small circular to subcircular pits or craters on fine-grained siliciclastic sediment surfaces. They may be associated with mudcracks (as are the modern examples shown above) and terrestrial fossils (such as fossil ferns). Locality: Black Rock Creek valley, just north of Black Rock, Leucite Hills, north-central Sweetwater County, southwestern Wyoming, USA |
