The overall tone of the discussions reflects strong agreement and high interest, demonstrated by mentions of new transitional species like Navajoceratops and Terminocavus, and comments on how these findings challenge previous models of dinosaur evolution. The tone and content show an active engagement with the detailed evidence and its broader implications for paleontology.
AgreementModerate agreement
Most discussions support the findings, emphasizing the significance of the research in understanding dinosaur evolution.
InterestHigh interest
The discussions show high engagement with the topic, highlighting its relevance in paleontology and evolutionary studies.
EngagementModerate engagement
Participants reference specific research details, such as the gradual skull changes and the evidence for anagenesis, indicating active engagement.
ImpactModerate impact
The posts suggest the research could influence current understanding of ceratopsid evolution and biogeography, indicating a modest but meaningful impact.
Abstract in brief
The discovery of three new chasmosaurine ceratopsid dinosaurs from the Kirtland Formation in New Mexico shows gradual evolutionary changes that link older and slightly more recent species, supporting the idea that these dinosaurs evolved through a process called anagenesis rather than rapid or branching evolution.
These specimens demonstrate a slow change in skull features, specifically the enclosure of the parietal embayment, which suggests a close evolutionary relationship between species from different time periods and regions.
The findings challenge previous ideas that separate these dinosaurs into distinct northern and southern groups, instead indicating that large-bodied ceratopsids moved freely across regions in the Late Cretaceous, reducing support for the idea of isolated faunal provinces.]

Basically the central embayment gets deeper through time (A-I, below from Fowler & Freedman Fowler 2020). Also note how the posterior bar of the parietal is thin and strut like (A, B) but then starts to get deeper and more rounded (C, F-H). From: https://t.co/UJE4JCOSOx https://t.co/ziMjZq34BX

This explosion of new taxa has led some researchers (Sampson & Loewen, 2010; Sampson et al., 2010) to propose that ceratopsids radiated through

@LancianIdolatry The maps show that during the mid Santonian, and at times Campanian, northern and southern parts of the Laramidia coastal plain were cut off from each other. This probably caused vicariance in various dinosaur lineages (e.g. chasmosaurines). Explained in https://t.co/Z2tUsBrHTZ
