The Glypheoidea are a group of lobster-like decapods that are primarily known to be fossilized . The Solnhofen limestone in particular is famous as a site. Another site is the "lobster bed" near Atherfield on the Isle of Wight , where numerous Mecochirus magna were found.
History of rediscovery
Originally it was assumed that the Glypheoidea were extinct. In 1975, however, a Neoglyphea inopinata was identified at the Smithsonian Institute . The cancer was caught during an expedition to the Philippines in 1908, but was never identified. Subsequent expeditions in the late 1970s and early 1980s caught additional specimens of this species . In 2006 another species of this genus, N. neocaledonica , was scientifically described .
In 2005 a new species was discovered in the Coral Sea off New Caledonia , which at the same time established a new genus . It was described as Laurentaeglyphea neocaledonica in 2006 .
The Glypheoidea are another example of living beings that have remained morphologically almost unchanged for a long time and are known as “ living fossils ”. Until it was rediscovered, it was assumed that this group of animals had already died out in the Eocene .
Systematics
The superfamily Glypheoidae comprises the family Glypheidae with three species still alive today and two extinct families:
- Family Glypheidae
- Family Mecochiridae †
- Family Pemphicidae †
