Stockings were usually black for daytime wear and white or colored for evening. They were held up by garters. By the end of the century, the garters were attached to the corset. Cotton drawers went over the stockings.
Cephalopods include squid, octopus, cuttlefish, nautilus, spirula, and the extinct ammonites and belemnites. Cephalopods first appear in the fossil record nearly 500 million ago during the Ordovician Period. They are all mollusks, members of the same Phylum Mollusca as oysters, conches, and the common garden snail.
By the late Devonian, 360 million years ago, early cartilaginous fish and bony fish were diversifying. The late Devonian also marked the first tetrapods -- vertebrates with true legs that could walk on land. By about 330 million years ago, in the Mississippian, several groups of land-dwelling amphibians had appeared.The oldest known amniotes -- close to the ancestry of all reptiles, birds, and mammals -- appeared in the early Pennsylvanian, about 310 million years ago.ut to give a very brief summary: The first known vertebrate fossils, found at the Chengjiang locality in China, date back to the early Cambrian. These early vertebrates, such as Haikouichthys, are small, tapered, streamlined animals showing eyes, a brain, pharyngeal arches, a notochord, and rudimentary vertebrae.
