Discovery

Both species of Cyllonium were first described by the English entomologist John Obadiah Westwood. The fossils were recovered from the Early Cretaceous (Berriasian age) of the Lower Purbeck formation, Durdlestone Bay, England.[2]

Taxonomy

Very little is known of the two fossils as they were published without description. Illustrations, however, were provided, but even these show that the fossils were fragmentary. They were originally identified to be butterflies, but this is now generally not accepted.[3]

They have been tentatively identified as possible palaeontinids (extinct giant cicadas) in 1961.[4]

Species

The two species assigned to the genus are the following:[2]

  • †Cyllonium boidusvalianum Westwood, 1854
  • †Cyllonium hewitsonianum Westwood, 1854
gollark: This is a values problem, not an economic system one.
gollark: The expected value of demanding for communism appears substantially lower than that of actually helping people with malaria.
gollark: Yet they do not do this, and instead ineffectually demand communism which would totally make everything great and wonderful.
gollark: Consider: the people complaining about wanting communism could probably work in a well-paying job, obtain money, and donate it to effective charities like the Against Malaria Foundation.
gollark: Capitalism seems to be doing a fairly okay job of satisfying the values of, well, people in places with more resources, and apparently most people's values don't actually involve helping people they don't directly interact with because humans are bad.
