Species: F. dorothea

Funisia is a genus containing the single species F. dorothea, a fossil upright worm-like animal from the Ediacaran biota.[1] Funisia stood about 0.3 metres tall.[2][3][4] Because individuals grew in dense collections of animals the same age, it is believed to have reproduced sexually.[3] Although the evolution of sex took place before the origin of animals, and evidence of sexual reproduction is observed in red algae 1,200 million years ago,[5] Funisia is one of the oldest known animals for which there is evidence of sexual reproduction.[4] Its relationship to other animals is unknown, but it may belong within the Porifera (sponges) or Cnidaria.[1] The genus and species were described in a 2008 paper.[1]

Etymology

The generic name Funisia is after the Latin "Rope", and is pronounced to rhyme with Tunisia, rather than the more fitting "fun is 'ere".[6] The name dorothea is in honor of Dorothy Droser, the mother of Dr. Mary Droser, one of the scientists who studied the organism. [2]
