Hi everyone, I found this small tooth over the summer in a Lance formation channel deposit in Wyoming. In the field I didn't know what to make of it, too recurved and compressed to be croc, no visible serrations either so probably not a non avian theropod. Months later I took a closer look at it and continued to search for its potential identity. I thought to myself could it be a mammal canine. After some online browsing I couldn't find a match for anything in the Hell Creek/Lance fauna. However, after posting it on an instagram story, I got a few suggestions. One of the more intriguing of those suggestions came from @Mioplosus_Lover24 who believed it was probably a varanoid lizard, potentially Palaeosaniwa. I looked for any images of Palaeosaniwa teeth online and came up empty handed, but I did find some similarities between my tooth and that of the Cretaceous Mongolian varanoid Estesia and a modern example of a monitor teeth. The length is approximately 6 mm and the width at the base is 2 mm. monitor skull I found online Estesia mongoliensis skull described in a 2013 paper by Norell & Yi

Hey everyone, I just wanted to post my find of the day! I was working through some of the Lance fm. channel deposit conglomerate from this summer's trip out west and when I was taking a closer look a bone fragment I noticed what appeared to be the glint of enamel just below it. I proceeded to uncover more of it and realized it was a tiny mammal tooth. It ended up coming loose from the matrix and I had to set it lightly on a piece of white paper as to avoid losing the minute fossil. Through closer inspection with my loupe I found that it had a morphology similar to a multituberculate tooth (cimolodon or mesodma) that I had found in South Dakota's Hell Creek during my trip. I am very pleased to have found this as there are little opportunities for me to find new fossils in November. Additionally, this may be the smallest tooth of any animal in my collection, and I'm proud I spotted it instead of overlooking it. Some perspective with a U.S. Penny (yes I know, not a valid unit of measurement, but it was the closest thing I had at that moment).
