I may have sent this directly to Dr. Holtz, but thought it may be of some interest to other members as well.
I've just read HP Holtz's paper on Tyrants' Phylogeny and Taxonomy in "Mesozoic Vertebrate Life" and have some questions(not necessarily directed to the author... answer freely if you feel).I apologyze if questions like these have already been answered in the past or if they're of obvious answer.
1)What do the "-"s in front of some character (as listed in appendix 7.3) mean? (e.g. -83.0 )
2)The Kirtland shale aublyosodontine is said to show the condition .2 for character n° 59, but in the character list there's no such state. Should it be 59.1 or is the 3rd condition for character 59 missing in the character list?
3) Could someone enlighten me on character 106 states? just can't visualize them....
thanks in advance
