Biology:Juracanthocephalus
From HandWiki
Juracanthocephalus is an extinct, monospecific genus of stem-group[1] acanthocephalan (thorny-headed worm) that lived in the Jiulongshan Formation during the Callovian age of the Middle Jurassic, 165 Ma.[2][3]
It shares features with both Seisonidea and Acanthocephala, suggesting they are sister groups, with Juracanthocephalus being a transitional form between the two.[3]
The type and only species is Juracanthocephalus daohugouensis.[3][4]
