Neostrachanognathus n. sp. A

Fig. 26 AD?

Number of specimens. 1

Remarks. Tat one specimen looks like it could be a P element of Neostrachanognathus as reconstructed by Agematsu et al. (2008). Since it possesses a posterior denticle, it does not belong to Neostrachanognathus tahoensis and may instead belong to Neostrachanognathus sp. A ( Agematsu et al., 2008) or to a different species. Tis element was found in middle Smithian strata together with representatives of Urdyella spp. If it does indeed belong to Neostrachanognathus it is its oldest representative.

Occurrence. Laren road cut, Luolou Formation, Smithian age, Nanpanjiang basin, South China.
