Juracanthocephalus is an extinct, monospecific genus of stem-group[5] acanthocephalan (thorny-headed worm) that lived in the Jiulongshan Formation during the Callovian age of the Middle Jurassic, 165 Ma.[1][2]
It shares features with both Seisonidea and Acanthocephala, suggesting they are sister groups, with Juracanthocephalus being a transitional form between the two.[2]
The type and only species is Juracanthocephalus daohugouensis.[2][4]
