This paleontological restoration is inaccurate, or its accuracy is disputed.
Reason: Reconstruction of "trunk appendages" questionable and may represent muscle/setal blades (according to Ortega-Hernández 2016); 11 trunk segment (12 in Schinderhannes); tail fan arose from terminal segment (attached point preceding terminal segment in Schinderhannes).
