    This might be Peniculauris bassi which is a very common brachiopod in the Permian Kaibab Formation. 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.…[Read more]

        Thank you so much for the information! I will change this and add some scale photos as well! I wasn’t really positive on the identification of this specimen. Thanks again! 🙂

    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…[Read more]

    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.

    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.
