An overview of the known fossil material of Tyrannomimus fukuiensis. Fossil specimens shown in are not in the same scale. The bar is scaled for the paratype (FPDM-V-10295). The holotype (FPDM-V-11333) and paratype in are colored in red and blue, respectively. The right femur in is mirrored from the left one (FPDM-V-11338).
