Rare Metoplolichas verrucosus Russian trilobite

Coming from the nearly half billion year old Lower Ordovician Wolhovian Level deposits of the Wolchow River region near Saint Petersburg, Russia, this is truly one of the very rarest Russian trilobites, the Lichid, Metoplolichas verrucosus. They are usually only seen as fragments: a pygidium, a partial cepahalon, etc. In over 15 years, this is only the SECOND the primary source of Russian trilobites has ever had found. While not as showy as its Lichid cousins of the genus Hoplolichas, it far outclasses them ALL in terms of rarity. Notice the many tubercules present on the the cephalon, genal spines, and pygidium, a commontrait of Order Lichida. The species name is derived from verrucose, meaning with warty excrescences; this one has them in abandance.
