Our largest tentaculitid yet from the Permian of AZ
Arizona Chris posted a topic in General Fossil Discussion
HI all, As we go through the latest acid fines from fossiliferous limestones from the Permian Fort Apache Formation at our new rich site on the Mogollon Rim, we now have a new specimen which is larger than dozen others we have obtained from this site over the past few years, a whopping 7mm long! The Permian was the very end of the span of these enigmatic fossils, the current thoughts are they were a lophophorate of some sort related to brachiopods and bryozoans. These Tentaculitids (say that three times real fast) are curved which is a bit rare, and etch out as hollow tubes with one end closed. Here the tip is missing, but you can see the general shape. More exciting finds are coming out of the fines, besides super tiny gastropods, we have found many urchin parts and some silicified trilobites as well. Ill keep you updated as we sort through the latest material! 10x microscope shot, mm scale at bottom.- 6 replies
