See plate 45 figures 1 and 2 in The Environment and History of Toroweap and Kaibab Formations of Northern Arizona and Southern Utah Volume 492 of Carnegie institution of Washington. https://babel.hathitrust.org/cgi/pt?id=mdp.39015009184303;view=1up;seq=333

It is silicified. I do not know what type of sponge it is. I am looking for an expert to help.
-
That’s very cool. I am pretty sure it is a demosponge. I found an occurrence through a paper and the PBDB on demosponges in AZ: https://paleobiodb.org/classic/displayCollResults?taxon_no=70272&max_interval=Permian&country=United%20States&state=Arizona&is_real_user=1&basic=yes&type=view&match_subgenera=1 but I think the location is quite different?
I’ll also tag in @mackenzie-smith to see if he has any ideas, he has a really broad knowledge of fossils.
-
@jbauer Sadly, no ideas this time. I know very, very little on sponges XD

Again it is packed away somewhere so I cannot add a scale. I believe measurements were provided. Sorry. Reference: A contribution to the invertebrate paleontology of the Texas Cretaceous: Texas Geological Survey Fourth Annual Report, pt. 2 by F. W. Craigin

Thank you, I can check out that reference!
The requests for scales are so that the curation team can help verify your measurements. It’s one of our image requirements for submission to iDigBio but certainly not required to be on the myFOSSIL eMuseum database. -Jen

I named it using the mentioned paper. I believe that measurements were provided in the data. Once again it is packed away somewhere so I cannot reshoot it with a scale. I have heard that you can add a scale next to the photo using the measurements provided.

It is packed away in a box somewhere. I am almost positive that the oral side was covered in cemented sand otherwise I would have provided a picture. Please include it in iDig with all associated data.

Thanks, John!

2 years, 10 months agoJohn Christian started the topic Early Women in Paleontology in the forum Women in Paleontology Forum
Check out this article about women who made important contributions to paleontology even though they were not allowed to join most scientific organizations. Pay special attention to the field collecting attire of both the men and women while on an outing; I could not imagine wearing these while collecting in Florida or Texas during the summer. At least the man on the far left looks a little more prepared with his pants pulled up and carrying a bag. I wonder if he had a tie?

What a great photo of your fossil. Detailed photos make our database more useful.

Agreed! My goal is 1-2 new images a week =]
