  1. Do you Know anything about this new officially unnamed theropod called Titanovenator Kenyaensis discovered in the Turonian deposit’s of Kenya’s Turkana Grit’s Formation and if please you could give me back info on this new animal and how would compare two the current big four theropod’s of today (TYRANNOSAURUS REX, GIGANOTOSAURUS CAROLINNI, CARCHARODONTOSAURUS SAHARICUS & SPINOSAURUS AEGYPTIACUS, thank’s bye)

    1. Thank you for informing me about this dinosaur. This blog focuses on prehistoric mammals so we dont have a lot of info on dinosaurs

  2. How would the Natodomeri Lion compare to the three largest species of pre-historic Pantherine cat’s known round the World today from the top of my knowledge on Big cat’s (American Lion, Mosbach Lion & Ngangdong Tiger) and have any there been more recent discoveries on larger specimen’s of Kenyan ice age lion’s been waiting to be published that you can give me sneak info on I mean Simbakubwa Kutokaafrikaa was discovered in 1978 but announced just only recently well I hope to get a good reply this time round thank’s.

    1. Going by the size of the skull, the Natodomeri lion is much larger than Atrox and Fosilis. Unfortunately, besides the one skull found, no other specimens of the Natodomeri Lion have ever been found

  3. What Hyeanodont’s where comparable in size to Simbakubwa Kutoaafrika in my birth place the United states of America & United Kingdom/Europe where I have lived for the last 33 year’s so you can see my curiousity with both sides of the Atlantic also tell me how you work out the American Lion & Mosbach Lion where smaller then Natodomeri Lion from what i’ve read it’s the other way around? Thank’s hope you reply.
