Well now, this is quite intriguing! It's nice to finally get some news on hell creek that doesn't involve tyrannosaurus

[Halichoeres]

A bit odd to name it after a vulture, even one with "chicken" in its nickname. Cool find, nevertheless.

The description of Anzu wyliei and the erection of the new genus Citipes for the Elmisaurus-like caenagnathid "Ornithomimus" elegans raised the question of whether or not MOR 752 (previously referred to elegans) is an elmisaurine or Anzu. The paper describing Eoneophron at least gives some resolution to this question by dropping hints about MOR 752 being a distinct taxon in spite of its juvenile nature. The description of Eoneophron also may indirectly support the notion that the holotype of Nanotyrannus lancensis and "Jane" could be their own taxon despite being immature individuals because Currie (2003) notes that no other tyrannosaurid taxon has been reported to have undergone an ontogenetic maxillary tooth reduction and the undescribed T. rex specimen KUVP 156375 reported by Burnham et al. (2018) has the same maxillary tooth count as adult T. rex despite being a juvenile (a publication describing KUVP 156375 in detail is essential to determine if the maxillary tooth count distinguishing adult T. rex and KUVP 156375 from CMNH 7541 and "Jane" is of taxonomic significance. After all, two different dromaeosaurid species are known from the Hell Creek Formation and more than one ornithomimid taxon is present in this geologic unit.
