However, until know, the only sure thing is that this animal was from Egypt, and probably from captive origin which will explain the great size and expecially the great wide of the skull.

To be honest is very hard to see the exactly size in the meter to the 1/16 of an inch, specially because of the curvatures and that some parts are not completelly flat, but IF I see correctly, the greatest length from incisors to the posterior end of the inion is about 16 1/4 in (413 mm) which means that excluding the incisors and taking the length from the anterior end of the premaxillary it will be about 407 mm; the byzigomatics arches are about 11 1/2 in (292 mm). This is in fact the widest skull from a lion that I know.

To make a comparison, the largest and widest wild-origin skulls from scientific records are 401 X 247 mm and 393 x 256 mm respectively, both from Southern Africa (Roberts, 1951). From captive specimens, the longest and widest skull that I know is a specimen of 410 X 300 mm from Egypt, probably a captive "Barbary" lion (Saber & Gummow, 2014). From Rowland Ward edition of 1975 the longest and widest skulls are 420.7 X 273 mm and 384.2 X 288.9 mm (it doesn't say if are "owner's measurements" or measured by Rowland Ward's company staff). Finally the extra large lion from Boneclones.com is of 393 X 278 mm.

With all these skulls for comparison, it seems that this "Lionzilla" skull match almoust perfectly with the giant lion skull from the Egypt museum. I will corroborate with the authors if the large skull is the same specimen from the National Circus in Egypt.

I have a very large database of wild and captive skulls, and the only "real" specimen that match the measurements of the "Lionzilla" skull is the the Egyptian specimen. Is posible that these two skulls are, in fact, one and the same?

Since Egypt belonged to the former range of the Barbary lion.

Though the Barbary lion of North Africa is the same subspecies as other formerly described subspecies, such as the Asiatic (https://web.archive.org/web/20070808182526/http://www.adelaide.edu.au/acad/publications/papers/Barnett%20PRS%20lions.pdf) and West African lions (https://www.nature.com/articles/srep30807?WT.feed_name=subjects_evolution; Page 72: https://repository.si.edu/bitstream/handle/10088/32616/A_revised_Felidae_Taxonomy_CatNews.pdf?sequence=1&isAllowed=y), Egypt has another formerly described subspecies which, unlike the Atlas lion, did not inhabit the rather temperate region of the Atlas Mountains, but the desert region of Nubia, which Egypt shares with Sudan. This was the Nubian lion (Panthera leo nubica), whose scientific name was often used for the East African lion (formerly Panthera leo massaica: https://web.archive.org/web/20170728131140/http://www.science.smith.edu/msi/pdf/762_Panthera_leo.pdf).

Do you know the MGM lion called 'Jackie'?

He was said to be from the Nubian desert of Sudan, so there you go, a Nubian lion: https://www.nj.com/opinion/index.ssf/2018/06/original_mgm_lion_rests_in_nj_other_historical_tid.html

Quantifying lion (Panthera leo) demographic response following a three-year moratorium on trophy hunting

The most important statistics from the work in my opinion:
"Closed mark-recapture models revealed a large increase in lion abundance during the hunting moratorium, from 116 lions in 2012 immediately preceding the moratorium to 209 lions in the last year of the moratorium. More cubs were produced each year of the moratorium than in any year with trophy hunting. Lion demographics shifted from a male-depleted population consisting mostly of adult (≥4 years) females to a younger population with more (>29%) adult males."

What do you think of the Lionzilla skull? Any thoughts?
