Description
Reconstruction of pterygotid eurypterids. Size not to scale.
top left: Jaekelopterus rhenaniae. Chelicerae based on Braddy et al. 2008 .
top right: Erettopterus bilobus. Based on Woodward 1866 with subsequent modifications.
center: Pterygotus anglicus. Based on Woodward 1866 with subsequent modifications.
bottom left: Acutiramus macrophthalmus. Based on Clarke & Ruedemann 1912 with subsequent modifications.
bottom right: Ciurcopterus ventricosus. Based on Tetlie & Briggs 2009 . The chelicerae are conjectural.
Cheliceral segmentation based on Selden 1984 (3 instead of 4-segmented, contra Kjellesvig-Waering 1964 ). Position of cheliceare and appendage II-V based on Bicknell et al. 2023b . Appendage II (pedipalps) of Jaekelopterus and Pterygotus are conjectural.
