Jaekelopterus rhenaniae
The species was first described in 1914 by German paleontologist Otto Jäckel from an isolated specimen named Pterygotus rhenaniae found near Overath in the Rhineland of Germany. Jäckel initially believed the fossil specimen to be typical of all pterygotids, such as Pterygotus buffaloensis, and therefore estimated the length of Jäckelopterus at 1.5 meters (4.9 feet).

"The ancient fish and their huge rival: Ideal restoration of Pterygotus, the huge extinct sea-scorpion nine feet long; with the earliest known fish Pteraspis, Cephalaspis, and small shark-like animals swimming among Stone-lilies, Trilobites, etc."

Paleo-Files: Pterygotus
Described by Louis Agassiz in 1839, Pterygotus, whose name means “winged one” in Greek, is a genus of raptorial Eurypterids or so-called “Sea-Scorpions” that thrived in the seas of North America, South America, Europe and Australia 428-372 million years ago from the middle of the Silurian period to the end of the Devonian. Pterygotus and its closest relatives such as Jaekelopterus can be distinguished from other Eurypterids for having spade-shaped telsions, large compound eyes that were similar to those of other predatory arthropods, and large chelicerae claws that were used for puncturing and grasping small prey such as small lawless fish and trilobites. and although the smallest species P.kopaninensis measured 50 centimeters long, many other species, such as the type species P.anglicus as well as P.impacatus and P.grandidentatus, could measure up to 1.6-1.7 meters (about 5.2-5.7 feet) long and were among the largest of the Eurypterids, only surpassed in size by Acutiramus and Jaekelopterus rhenaniae.
Gerrothorax, Pterygotus, Pikaia, Enchodus, Hallucigenia, Arganodus, Tullimonstrum, Haimirichia, Hibbertopterus, Amiskwia, Opabinia, Hyphantoceras, Ottoia, Tiktaalik, and Cameroceras! Not to scale.
Honestly if I knew I was gonna add so many for this one I would’ve made more room
