An oviraptorosaurian from hell creek formation.
Lamanna et al.
The oviraptorosaurian theropod dinosaur clade Caenagnathidae has long been enigmatic due to the incomplete nature of nearly all described fossils. Here we describe Anzu wyliei gen. et sp. nov., a new taxon of large-bodied caenagnathid based primarily on three well-preserved partial skeletons. The specimens were recovered from the uppermost Cretaceous (upper Maastrichtian) Hell Creek Formation of North and South Dakota, and are therefore among the stratigraphically youngest known oviraptorosaurian remains. Collectively, the fossils include elements from most regions of the skeleton, providing a wealth of information on the osteology and evolutionary relationships of Caenagnathidae. Phylogenetic analysis reaffirms caenagnathid monophyly, and indicates that Anzu is most closely related to Caenagnathus collinsi, a taxon that is definitively known only from a mandible from the Campanian Dinosaur Park Formation of Alberta. The problematic oviraptorosaurs Microvenator and Gigantoraptor are recovered as basal caenagnathids, as has previously been suggested. Anzu and other caenagnathids may have favored well-watered floodplain settings over channel margins, and were probably ecological generalists that fed upon vegetation, small animals, and perhaps eggs.
Supercommunist: The claims aren't crazy but I just find it a bit annoying how some of the most popular animal youtubers tend to have a pretty medicore grasp of the subject.

Supercommunist: He also claimed that corvids cannot reliably kill anything larger than an insect.

Supercommunist: Tier zoo repeated the myth that birds have weaker, hollow bones in their most recent video.

Supercommunist: Anyone know any accounts or rabbits straight up killing stoats/weasels? Also, any accounts of stoats attacking and killing hares?

dinosauria101: I will never understand the purpose of dishonest streaming services that list full seasons and episodes of shows there's no option to watch.

Infinity Blade: Indeed it will be (I remembered that I'll be turning 25 this year), so I think this would be a perfect opportunity.

Exalt: Seems it aired in October and November, so close.

Exalt: Wait, isn't this the 25th anniversary of wwd anyway, if it aired in 1999?

Exalt: I've pondered the idea of doing it myself, there's stuff to comment on, but I've not seen much in the way of reviews for it. Weirdly, WWB seems more popular to do.

Exalt: I'm not going to push you either way, just an observation that I made.

Infinity Blade: I first started doing reviews as a means to celebrate an anniversary (like the 20th anniversary). Then I started being less stringent on that, so if I wanted, I could review WWD.

Exalt: Also, it sure is crazy how despite how limited the fossil record is in the grand scheme of natural history, we're still making discoveries on a relatively frequent basis.
Jan 25, 2024 4:55:00 GMT 5
Exalt: I just looked through the documentaries board and if I've not missed it, nobody has actually done a review for WWD. Huh.

creature386: @hammerhead Just so that we're clear, it's me who is rejecting your alt-accounts over and over again, not Infinity Blade. IB can't even see your insults unless I show him (which, admittedly, is a fun past-time activity of ours).

Exalt: Or, debated, rather.
