These fewer number of raindrops impact upon ...The more abundant trace fossil record of the downstream facies can be seen to be directly correlated with the number of bedding planes that can be recognised as true substrates (either by their surficial trace fossils, MISS, or other physical sedimentary structures such as raindrop impressions or ripple marks) (Fig. 17).

Raindrop impressions: Tiny craters created by raindrops as they impact the bedding plane surface. Horizontal strata: Relatively flat layers of sedimentary rock (è 1 cm thick) and laminations (< 1 cm thick). Current ripple marks: Asymmetrical wave-like structures. The steep slope faces down current, and the gentle slope faces up current.The sizes of raindrop impressions depend on raindrop velocity, the atmospheric pressure and the composition of material into which the raindrops fall. Previous research has shown that at Earth's ...They frequently reveal patterns that are strikingly familiar from modern sedimentary environments, such as ripple marks, animal trackways, raindrop impressions or mudcracks: all phenomena that are apparently ephemeral in modern settings, and which form on recognizably human timescales.
Raindrop imprints will only form when loose sediments are impacted (see examples below). Raindrop imprints (above & below) on mudshale.

You could call them raindrop impressions if you want to avoid using an overly broad definition of 'fossil'.

Petoskey Stone: Fossil coral in limestone . A Petoskey stone is a rock and a fossil, often pebble-shaped, that is composed of a fossilized rugose coral. Such stones were formed as a result of glaciation. matrix.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).
raindrop impressions in Chinese : 雨痕…. click for more detailed Chinese translation, meaning, pronunciation and example sentences.In order for raindrop impressions to be preserved in the rock record, the impression would have to have occurred towards the end of a rain shower. The decreased number of impacts at this time accounts for the scattered patterns of the impressions, and the specific saturation of the sediment allows for preservation.Raindrop impressions form on muddy surfaces. Horizontal strata occur where sediments settle from water or air; or where air or water currents move parallel to the surface on which sediments are accumulating. Current ripple marks occur in any environment where wind or water currents move in only one direction for a period of time: wind blown ….
