Cf Th Ryothorus Sp

REFERRED MATERIAL Distal mandibular symphysis, DMNH 8528.

provenance Location 644, Velvet Room, grid 1, level 10 (mixed).

DESCRIPTION This specimen is larger than those in Salpinxes obsoletus, Troglodytes aedon, T. troglodytes, Thryomanes bewickii, Catherpes mexicanus, Cistothorus platensis, and C. pa-lustris, and distinctly smaller than that in Campylorhynchus brunneicapillus. It compares most closely in size and features to Thryothorus ludovicianus, but in lateral view the dentary in this species begins curving downward sooner than that in the fossil specimen. This specimen may represent an extinct species of wren, but additional material and further comparisons to living taxa are needed.
