2 days, 2 hours ago2 days, 2 hours agoThank you, @samantha-ocon! This marvelous specimen certainly appears to be Placenticeras sp. (as @delwin-glasner noted) of the Campanian Age, although I cannot tell the species of this notoriously ‘difficult’ genus; here is a relevant paper that may be of interest:
William Aubrey Cobban. (2016). “A survey of the Cretaceous ammonite Placenticeras…[Read more]

Thanks, the suture pattern appears to have the shape of oak leaves. Survey referenced suture pattern look a little different. You are right, it is difficult.

5 months, 1 week ago5 months, 1 week agoThank you, @jbauer! As Jen said, I am a high school-aged geologist-in-training with a great interest in sedimentology and paleontology, which I have studied to graduate-level readings. While most of the time I am studying Quaternary geology, my ‘specialties’ in paleontology would be ichnology, diapsids, and cephalopods, although I investigate oth…[Read more]

5 months, 2 weeks ago5 months, 2 weeks agoHello @jbauer, thank you for your comment! I was just about to ask you about this specimen’s identity. Actually, I found this in a fairground parking lot and off the top of my head I thought it resembled some Oligocene brachiopods here in Washington State, but after looking more into it I doubt that it is local. I will update it and if you have…[Read more]

Let me tag in @mackenzie-smith who is more familiar with PNW fossils to chime in on the potential origin. I’ve collected similar looking fossils from the Ordovician – but certainly they extend beyond that time period. Oligocene just seems a bit too far – but I’m not super familiar with brachiopods outside of the Paleozoic.

5 months, 2 weeks ago5 months, 2 weeks agoHello @jbauer, thank you for the clarification! It is unfortunate that such an interesting field lacks a comprehensive yet simple specimen classification yet, although perhaps that complexity is what makes it so interesting!

Hi, @i-edwards – are you sure this was found in Oligocene rocks? It looks very similar to other brachiopods I have found that went extinct in the Permian, namely Lepidocyclus and Hiscobeccus. PBDB is suggesting maybe there are some Oligocene occurrences: http://fossilworks.org/bridge.pl?a=taxonInfo&taxon_no=86574 but it jumps from the Devonian to…[Read more]

@jbauer and @i-edwards Get ready for a long answer! WA has rocks from almost every period in the Phanerozoic. The PBDB also has a lot of omissions from PNW fossils since many of the original collections were USGS, have been lost or were never cataloged into PBDB. So it would not surprise me if this was an Oligocene occurrence that is not it PBDB.…[Read more]

Yay! I love long answers! Thanks, @mackenzie-smith. I figured there was a lot of information ‘missing’ from all the online databases in terms of specimens & lithologic information.
From what I remember the strong ribbing decreases through time – which was the first big trigger for me that maybe something was a bit off. I can try to track down an…[Read more]

5 months, 2 weeks ago5 months, 2 weeks agoThank you, @sadie-mills and @jbauer for your comments! Unfortunately, classifying ichnossils simply can be so difficult because of the different system it uses! It emphasizes ethology over bauplan because rarely do we exactly know what the producer is (one of the founding principles of ichnology). I think that Kingdon Animalia > Phylum…[Read more]

Hi, @i-edwards – I have taken a few ichnology courses and appreciate your sentiment but the issue is with the underlying structure of the data – which is a global standard. We can add fields as we like but I’m not sure a separate standard exists for ichnotaxa. I can chat with some colleagues about it at GSA.
We *do* have a Field Notes section…[Read more]
