Cucullaea Gigantea

picture info	Cucullaea Gigantea ''Cucullaea gigantea'' is an extinct species of false ark shell found in the United States, in the Aquia Formation in Maryland and Virginia along the Potomac River and its tributaries, and in Alabama. They flourished in marine environments during the Paleocene The Paleocene, ( ) or Palaeocene, is a geological epoch (geology), epoch that lasted from about 66 to 56 mya (unit), million years ago (mya). It is the first epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), E ..., ranging from 58.7 to 55.8 million years ago. ''Cucullaea gigantea'' average about 8–14 cm in length, about twice the size of its relative ''Cucullaea'' ''recendens'' which average 5–8 cm. ''Cucullaea'' were infaunal suspension feeders, meaning they burrowed into the seafloor and strained their food from the water.

	Aquia Formation The Aquia Formation is a geologic sandstone formation that extends from the upper Chesapeake Bay to the James River near Hopewell, Virginia. It consists of clayey, silty, very shelly, glauconitic sand. Fossil records indicate that this stratigraphic unit was created during the Paleocene. The Aquia formation was named for Aquia Creek where it is exposed in cliff faces along the banks. Geology Lithology When uncovered, it appears dark green to gray-green, argillaceous, with well sorted fine- to medium-grained sand and locally indurated shell beds. It is between 0 and 100 feet thick in Maryland. Quartz and phosphatic pebbles and/or very coarse glauconitic quartz sand mark the base of the unit. A few hard streaks of shells or thin "rock" layers are often reported but appear to be more abundant in the sections south of the James River. Stratigraphy The Aquia formation is overlain by the Nanjemoy Formation and overlies the Brightseat Formation. The Aquia formation is brok ...

picture info	Paleocene The Paleocene, ( ) or Palaeocene, is a geological epoch (geology), epoch that lasted from about 66 to 56 mya (unit), million years ago (mya). It is the first epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name is a combination of the Ancient Greek ''palaiós'' meaning "old" and the Eocene Epoch (which succeeds the Paleocene), translating to "the old part of the Eocene". The epoch is bracketed by two major events in Earth's history. The K–Pg extinction event, brought on by Chicxulub impact, an asteroid impact and possibly volcanism, marked the beginning of the Paleocene and killed off 75% of living species, most famously the non-avian dinosaurs. The end of the epoch was marked by the Paleocene–Eocene Thermal Maximum (PETM), which was a major climatic event wherein about 2,500–4,500 gigatons of carbon were released into the atmosphere and ocean systems, causing a spike in global temperatures and ocean acidification.
