What Left These Odd Fossilized Tracks?

At lengths upwards of 6 feet (1.8 m), Arthropleura was the largest land-dwelling arthropod of all time. Its many legs sprouted from around 30 jointed segments covered in armored plating, segments of which have been discovered by paleontologists. Due to its size, Arthropleura probably had few, if any, enemies. Scientists believe that it ate dead plant matter just like its living millipede descendents. These gigantic bugs became extinct when the climate shifted, drying out the sprawling swamps in which they lived.
