.... In South America, out of 119 references we identified 79 sites where palaeoshorelines were created during the last interglacial maximum (MIS 5e, 122 ka). At all sites, this particular palaeoshoreline (referred herein as MIS 5e palaeoshoreline) is embedded in a coastal sequence whose formation may have...
