The collective discussions demonstrate a high level of interest and engagement, with participants discussing the evolutionary processes (like anagenesis) and stratigraphic evidence supporting the findings. The tone reflects a mix of scientific curiosity and recognition of the article’s importance in paleontological research, as seen in references to specific specimens and comparative studies, indicating the group's overall support and recognition of the work’s significance.
AgreementModerate agreement
Most discussions support the article’s conclusions about the evolutionary trends in Triceratops, with many referencing stratigraphic data and development patterns.
InterestHigh interest
There is strong curiosity expressed, especially with mentions of evolution, stratigraphy, and dinosaur morphology, indicating high engagement with the topic.
EngagementModerate engagement
Participants delve into scientific concepts like anagenesis, ontogenetic variation, and stratigraphic context, showing meaningful analysis and reference to other research.
ImpactModerate impact
The discussions highlight how this research influences understanding of dinosaur evolution and stratigraphy, though it remains within academic and enthusiast circles rather than broad societal impact.
Abstract in brief
The study analyzes over 50 Triceratops skulls from Montana's Hell Creek Formation, showing that two main morphospecies, T. horridus and T. prorsus, are found at different stratigraphic levels, with T. horridus lower and T. prorsus higher, indicating a chronological evolution.
Transitional forms in the middle of the formation suggest that Triceratops evolved mainly through anagenesis (gradual change within a lineage) rather than significant branching or speciation events.
The findings highlight the importance of stratigraphic data in understanding dinosaur evolution, suggesting that some morphological differences are due to evolution over time rather than sexual or developmental variation within a single species.]
@Riamus01 While there seems to be a good deal of individual variation between trike specimens, most of the striking differences are actually ontogenetic and stratigraphic. See Fowler & Scannella 2014 for details

@Pathfinder4545 @Mwforhr @robjGoldberg @LancelotAmeric1 @Masks4Life @wendelltalks What are these “basis claims” that aren’t testable or replicable? Why is it that I can keep citing papers which make testable and replicable hypotheses and then actively test them in the same paper? https://t.co/IE3sUb6YmR
Show me how this paper doesn’t use the scientific method
@SeptembersRain @TakeThatDarwin @AwayFromTheKeys @LiberTDayWalker And we can even look at the evolutionary history of different lineages using fossils! Seeing morphological change over time as predicted by evolutionary theory.

And these are just dinosaurs… and not all the examples in dinosaurs either
@ARuebenstahl I mean, it is published: https://t.co/UWXDJyYgzs
I can’t comment further on the “validity” of the discourse since I lack credentials in the field, but it reads pretty sound.
