Ancalagon (worm) (original) (raw)
L'ancalagon (Ancalagon minor) è un animale estinto, appartenente ai priapulidi. Visse nel Cambriano medio (circa 505 milioni di anni fa) e i suoi resti fossili sono stati ritrovati in Nordamerica, nel ben noto giacimento di Burgess Shales.

| dbo:abstract | Ancalagon minor is an extinct priapulid worm known from the Cambrian Burgess Shale. Because it superficially resembles the modern-day internal parasites known as the acanthocephalids or "spiny-headed worms," A. minor was once thought to be, or once thought to resemble the hypothetical free-living ancestor of acanthocephalids. Two specimens of Ancalagon (worm) are known from the Greater Phyllopod bed, where they comprise < 0.01% of the community. Along with the other Cambrian worms such as Ottoia, Selkirkia, Louisella, Fieldia, Scolecofurca, and Lecythioscopa, the organism may fall into a clade termed "Archaeopriapulida," a stem group to the Priapulids proper. However, the morphological similarity of these organisms to their modern cousins is remarkable, especially for the Burgess Shale. A phylogenetic analysis does not provide a great deal of resolution to the relationships between these basal worms.
