The upper Campanian deposits of the Dinosaur Park Formation at Muddy Lake, Saskatchewan, are known to contain the bones of one or more horned dinosaur species, but definitive diagnostic material has remained elusive. Here, we describe a newly recognized partial parietal from these deposits, bearing a single spike-like epiossification that projects posterolaterally from the frill margin. The element is most plausibly attributable to the centrosaurine Spinops sternbergorum, a species otherwise known only from Dinosaur Provincial Park, Alberta. Juvenile ceratopsids appear to be relatively abundant at the Muddy Lake locality, which was proximal to the Western Interior Seaway. We suggest that such lowland coastal settings might have been important breeding grounds for horned dinosaurs.

Anyone else notice this is in a 2024 volume but published in 2025? What's up with that?

This has also been the case for the Journal of Vertebrate Paleontology for the past several years- their volume's publication dates don't match up with the actual publication dates of the articles. And not in a way like Historical Biology where it takes years to get the online versions in a volume, but the reverse. For instance, if you go to Volume 44 which is said to be from 2024, with every issue also supposedly from 2024 ( List of issues Journal of Vertebrate Paleontology ), in Issue 4 every article was published online in February 2025. Issue 5 is April-May 2025, and so on. So technically all of those papers should be cited "2025 as 2024" or something. The pdfs have no mention of volume or issue numbers, or page numbers for that matter. I do wonder if the physical journal articles are identical, but I haven't held a paper JVP in over a decade. I contacted Michael D'Emic about it back in April but never heard back. Anyone know what's up?

JVP got delayed in 2020 and still hasn't caught up. Crazy year that was. The print versions have only their "intended" date (ie about a year prior their actual publication date) on the cover but each paper within has the same dates as there would be on PDF version. Pagination is by paper, so it starts from 1 at the beginning of every paper. Print version has the same page numbers as the PDFs.

The "lag" predates 2020. I probably first noticed it with the description of Sequiwaimanu, which was online first in 2018 but backdated to 2017.

Thanks for the correction Alb. 

I became aware of it in 2020 and assumed it was recent given pretty much everything was being delayed and disrupted that year.

I would think the more logical course of action would be to just make the 20XX volume smaller or not print it, then keep the papers in the correct year's volume. Or just label the volumes as the correct year range, so just call Volume 44 "2024-2025", which was how a lot of old journals did it back when there were less papers to publish. In a sense it doesn't matter because who reads paper journals still anyway? You just search for the DOI, e article number or title. But it's also weird that the papers themselves don't even include a volume or issue, unlike every other paleontology journal I can think of that has volumes and issues. Maybe the SVP is planning a move to electronic only in the foreseeable future so will just use the article number like some e-only journals do now, and thus they don't care about fixing the situation?

And yes, the problem started in 2017, Volume 37 Issue 6, where four papers are from February 2018. I guess keeping volumes the same length would be to make it fair for subscribers (= SVP members, because there's not even a listed price for non-members-  Subscribe to Journal of Vertebrate Paleontology ). So they just should have called Volume 37 and Issue 37(6) specifically both 2017-2018, etc..

JVP has long had issues. A good while back I rolled the dice and for some reason submitted a paper. They had a rule that even before they would consider it for review the entire manuscript had to fully conform with their formatting down to the last wee detail, only journal I knew that did that (some will accept any formatting, will require reformatting only if accepted). They sent it back with needed changes. OK. Sent it back with more needed changes, including down to the exact dash line -- formatting they listed. I did not understand what the obscure formatting terms they were using. Tried to do that. JVP sent it back for more formatting. I was getting fed up, sent it back with a last round of redo and said to them to decide whether or not to send it for review as it is. They said no. Never sent another paper there. From what I understand they have since dropped the extreme pre-review requirements.

Yes, I remember JVP's weird persnickettiness in this regard. I gritted my teeth and went through it for my 2009 paper on Giraffatitan and Brachiosaurus, but having got that one into the journal I've never felt a need to go back there that's strong enough to make me go through all that again.
