These Goniatites derived from the Middle Donovan some 390 Million years ago. The colors vary from browns to grays and whites. Nautiloids, unlike the ammonites, have straight or slightly curved sutures. Goniatite sutures have smooth saddles and lobes and some Goniatite ammonoids have a distinctive zigzag pattern.
