Han.T Posted June 8, 2014 Share Posted June 8, 2014 (edited) Hi all, I am interested in acquiring this crinoid from an old shop in Chinatown. The store owner told me he brought it out of China decades ago but does not know the ID. My own amateur guess is Traumatocrinus but can anyone else give some insight on this? Below are a few pictures of the specimen, which measures about 1 ft(12") in length. I will detail the Chinese dragonfly in the next post. Edit: forgot about the measurements!

Han.T Posted June 8, 2014 Author Share Posted June 8, 2014 (edited) I also have a fossil dragonfly(?) from China as seen in the photos below. The specimen measures a little over 4 inches in length. My closest guess is Sinaeshcnidia cancellosa but again there is not much information I can find on Chinese dragonflies and hope someone here could help me. Thank you everyone for looking at my posts!

CH4ShotCaller Posted June 8, 2014 Share Posted June 8, 2014 I can't name either piece, but I gotta say, "those are very nice"! Is the dragonfly in a concretion? The crinoid is certainly worthy of a center piece for a display. Thank you for sharing this, very nice indeed!

Mr_ed Posted June 8, 2014 Share Posted June 8, 2014 Very nice.. I wouldn't hesitate too long before making the purchase, it would be my luck that it was gone when I went back for it. Such detail.. Hope it is still there when you go for it.. Ed Link to comment Share on other sites More sharing options...
piranha Posted June 8, 2014 Share Posted June 8, 2014 Hi Han, The genus spelling is off by a letter (should be Sinae-sch-nidia) preventing you from finding any useful results in the literature. There are numerous references to research and apparently the correct name is Aeschnidium heishankowense which was synonymized from Sinaeschnidia cancellosa (Hong, 1965) Ren et al., 1995. Hong, Y. (1965) A new fossil dragonfly, Sinaeschnidia Hong gen. nov.(Odonata, Insecta). Acta Entomologica Sinica, 14(2):171-171 Ren, D., Lu, L., Guo, Z., & Ji, S.

Han.T Posted June 8, 2014 Author Share Posted June 8, 2014 Thank you all for your kind comments, and Scott for once again providing excellent sources for reference! I am still trying to confirm the ID of the crinoid, it seems there are two types of matrix that specimens of Traumatocrinus hsui have been found preserved in(black and brown)...
