These environmental associations only reflect understanding of
subaerial temperature exposures.
Cosmarium is characterized by having generally solitary cells, semicells rounded, reniform, pyramidate, quadrate with entire or undulate margin; subcircular to elongate-oval (biradiate) in apical view; cell wall smooth with scattered pores or ornamented; one to several chloroplasts per semicell, axial or parietal, and as well as other desmids generally inhabit acidic, oligotrophic, aquatic environments and occasionally
subaerial or in basic, eutrophic water (Guiry and Guiry, 2017).
Subaerial Bone Weathering and Other Taphonomic Changes in a Temperate Climate [master's thesis].
Qualitative and quantitative analyses of secondary metabolites in aerial and

A rheologic classification of

4), which arguably represents a deeper-water environment than Narke, provide convincing evidence of
subaerial conditions.
Aerophilous species that dominate in the diatom composition occur commonly in
subaerial environments, i.e.
Before that time, there were two widespread death events (at about 30,000 years and 22,000 years ago) caused by exposure of the reef to air, known as
subaerial exposure, as sea levels dropped over the millennia.
In 1991, the Limon Earthquake caused coastal uplifting of the Caribbean coast (Cortes, Soto, Jimenez, & Astorga, 1992; Cortes et al., 1994; Cortes & Jimenez, 2003), which resulted in the
subaerial exposure and subsequent die-off of more than 40 000 [m.sup.2] of seagrass (Cortes et al., 1992; Cortes et al., 1994).
In the BOF eustatic lowering would have resulted in exposure to
subaerial conditions for large areas along the coasts, prior to the return to amplified high tides over the last 7000 yrs.
