Figure 9. Thatchtelithichnus holmani. All scale bars are 5 mm. Photographs (1) through (5) are all from a single cf. Echmatemys sp. specimen (UA-TF149). Note the occurrence of both Karethraichnus taxa and Thatchtelithichnus on these bone fragments. (1)Central part of T. holmani on central portion of hypoplastron. The holotype of Thatchtelithichnus holmani is identified with an arrow. (2) Peripheral fragment of hypoplastron showing several T. holmani as well as pit-like K. lakkos and deep, cylindrical K. kulindros.(3, 4) Left epiplastra with several T. holmani.(5) Hyoplastron fragment with several T. holmani.(6) Hyoplastron fragment with single, large T. holmani (UA-TF150). (7) Hyoplastron fragment with several T. holmani (UA-TF151). (8) Left epiplastron with single T. holmani (UM102773). (9) Hyoplastron fragment with single T. holmani (UA-TF152). (8)and (9) have only slightly enraised central platforms and may be an intermediate form between T. holmani and K. lakkos. All scale bars 5 mm.
