Soliclymenia is an extinct genus of ammonite from the Late Devonian. There are various species in this genera including Soliclymenia paradoxa, Soliclymenia semiparadoxa, Soliclymenia solarioides and Soliclymenia recticostata. While S. solarioides and S. recticostata have circularly-coiled shells, S. paradoxa has an unusual, triangularly-coiled shell. S. semiparadoxa, which is known only from the holotype, is semi-triangular, the innermost whorls being circular.
