C. nasicornis holotype waxaa laga helay iyadoo la joogo lakabka bidix ee bidix oo ay kujirto gacmo aan dhamaystirnayn. In kasta oo la kala saaray intii lagu jiray diyaarinta, waxaa laga sameeyay qalab laga sameeyay burburka ka hor si loo diiwaangeliyo jagooyinka asalka ah ee lafaha. Lafaha Carpal looma aqoonsan nooc kasta, taasoo keentay in qoraayada qaarkood ay soo jeedinayaan inay ku lumiyeen jilibka. Warqad 2016 ah, Matthew Carrano iyo Jonah Choiniere waxay soo jeediyeen in hal ama in ka badan carpals cartilaginous (aan lafta lahayn) ay u badan tahay inay ahaayeen, sida lagu tilmaamay by lafdhabarta u dhexeeya lafaha gacanta iyo lafta hore, iyo sidoo kale sida qoraalka guud ee dusha sare ee la arkay inta badan farqiga u dhexeeya labada asalka.
