The '''El Mamey Formation''' is a geologic formation in the Dominican Republic. The formation consists of [[Chemistry:Shale|shale]]s and [[Earth:Sandstone|sandstone]]s interspersed with a [[Earth:Conglomerate (geology)|conglomerate]] of well-rounded pebbles, deposited in a fluvio-deltaic [[Earth:Depositional environment|environment]]. El Mamey Formation is one of the formations containing [[Earth:Dominican amber|Dominican amber]] and preserves fossils dating back to the [[Earth:Burdigalian|Burdigalian]] to [[Earth:Langhian|Langhian]] period.<ref>[http://www.fossilworks.org/cgi-bin/bridge.pl?a=collectionSearch&collection_no=75094 El Mamey Formation] at [[Biology:Fossilworks|Fossilworks]].org</ref>
