Yeah, that was also my initial thought. I just wanted to verify if anyone else found that odd, since I'm right now working on an entry for the German Wikipedia.
Fun fact: I also wrote a profile for Lythronax in the German Wikipedia, the oldest tyrannosauroid in North America until Moros came along.

There's a new hyainailourine called Simbakubwa kutokaafrika. We got a massive body mass estimation range from three different body mass estimation methods (though, only two of those three are needed to convey the margin of error). Simbakubwa is estimated to weigh anywhere from 280 to 1,554 kg. The latter is highly suspect IMO, but bottom line, new hyaenodontid from the Miocene of Kenya. www.tandfonline.com/doi/full/10.1080/02724634.2019.1570222 |

^Was that last estimate derived with a suspect method? There are many cases of extinct mammalian carnivores being oversized because of bad estimation methods

There are many cases of extinct mammalian carnivores being oversized because of bad estimation methods Well, all of them were extrapolated from tooth measurements, so yes, you could say that. The only meaningful bottomline of those estimates is basically "it was large", but not how large. Also note how the estimates for Megistotherium are even higher, up to 3t, which it ridiculous. In any case, the largest known Megistotherium specimens have larger teeth than this new taxon. |

Anyhow, like you, I don't think I buy 1.5 tons. More likely it was 300-500 kg or so, unless we have solid evidence of larger sizes. |

From the dental measurements and regressions presented in the same paper, that’s the point. |

I think there's an old video of mine (Zuniceratops vs Planet Dinosaur Tyrannosaurid ("Zunityrannus")) that needs renaming. Looks like the title was already inaccurate back then. I've just checked the Suskityrannus article and, contrary to what many people told me, "Zunityrannus" was no name Planet Dinosaur made up.

Hmm. If Planet Dinosaur didn't make up the name "Zunityrannus", who or what did? It was the only work/source I could trace the name back to.

According to Wikipedia, the word was mentioned in Zuniceratops' description paper.

Yi Qi now has a new cousin called Ambopteryx longibrachium who lived in the Oxfordian stage (~163 mya) of what is now China: www.nature.com/articles/s41586-019-1137-zApparently, membrane-flight was an early, unsuccessful experiment during the evolution of powered dinosaur flight. Here's a video for those who want to see the bat-dinosaur-bird thing in action:
