Auchenaspis salteri is an extinct species of armored jawless fish of the order Thyestiida from the Late Silurian of England .[1][2][3] In England, A. salteri's fossils are found in extreme abundance in the Lower Old Red Sandstone strata in Ledbury, Herefordshire.[4]
A. salteri strongly resembles the thyestiids Procephalaspis and Thyestes, and within Thyestiida, it represents a transitional form between the primitive, superficially Cephalaspis-like forms, such as Thyestes, and the more specialized tremataspid thyestiids, like Tremataspis, Dartmuthia, or Dobraspis, whose headshields tend to resemble hot buns or horseshoe crabs.[5]
