Looking back over the past 15 years (going back to the Thescelosaurus! days), 2012, 2013, 2014, 2015, 2017, kind of 2018, 2022, and now 2023 would count. Why this should be I don't know, since it doesn't seem to affect other groups.Justin Tweethttps://www.blogger.com/profile/01792470288586894872noreply@blogger.comtag:blogger.com,1999:blog-6574000839639433662.post-292459559047587662023-04-07T11:28:02.814-05:002023-04-07T11:28:02.814-05:00Two months later and Chucarosaurus is still the on...Two months later and Chucarosaurus is still the only non-avialan Mesozoic dinosaur named from 2023.
