The type species Heightingtonaspis anglica was described by Ramsay Traquair in 1890, and was initially named Phlyctaenius anglicus. The holotype specimen NHMUK PAL PV P 29417 was first discovered on the surface at the Old Red Sandstone supergroup, Shropshire, England and the fossils were radiocarbon dated in situ to 416 million years old.[1][2][3] it has also been found in the Senni Beds of Wales.[3]
Heightingtonaspis clarkei was described by Charles R. Eastman in 1907, and was originally named Kujdanowiaspis clarkei. It was later revised and reassigned to the genus Heightingtonaspis by Denison in 1978.[1][4]
Heightingtonaspis willsi was described by White in 1961, and was originally named Kujdanowiaspis willsi, but was later reassigned to the genus Heightingtonaspis, which was created in 1969 by White.[4] H. willsi was discovered in the same location as H. anglica, in Shropshire, England.[1][2][3]
Heightingtonaspis is one of the more basal members of the order Arthrodira, as shown in the cladogram below:[5]
