sentences:  The specimen might have experienced some disarticulation postmortem (or could represent a partial exuviae), but as there is no apparent disarticulation in the metasoma, it is likely that the articulation seen in the postabdominal segments would have been possible in life (which is also seen in some other eurypterid fossils, such as of "Eurypterus" and "Alkenopterus").Biomechanical studies on the telsons and postabdominal segments of closely related eurypterids, particularly those of the family Pterygotidae, has revealed that the body was very stiff, and that the flattened telson would likely have served a function as a rudder that would have allowed the animals to be agile and capable of quick turns when chasing after prey, contradicting previous hypotheses that they would have served a propulsive function.Whilst the postabdomen of "Slimonia" was likely similarly stiff and inflexible dorsally (up and down), the study of the specimen suggests that it was highly flexible laterally (side to side).
