    Echinometra mathaei

    From the album: Holocene

    Echinometra mathaei, Maui Holocene May, 2023

    Fossil echinoids?

    I’ve found two of these in a gravel area in my front apartment area I remember buying the bags at a popular hardware store, I was told they are Echinoids, at first I thought they must have been something I collected and threw there but these are not common in my part of California. As far as I know. Any idea what species these are and where they might have originated? I’m tempted to buy another bag.

    Holaster simplex

    Gauthieria sp.

    From the album: Ozan Formation

    Gauthieria sp., Travis Co. Campanian, Cretaceous Oct, 2022 My friend Lari gifted me the NSR guidebook and I found this name while reading through it. After some searching online it seems to match up with this urchin I found in the Austin Ozan last year. The tubercles are imperforate and crenulate. Gauthieria has been found up north in the NSR, but is extremely rare. In Austin I've found so far this compressed specimen which I sadly broke trying to extract (still kicking myself) and a smaller fragment still in my collection. I'm gonna have to make a return trip to the spot
  5. Hey everyone! A few weekends ago I did my second-ever fossil hunting trip at the well known site of Beaumaris Bay in Melbourne. I was hoping to find a shark tooth, and we did bump into a fellow hunter who had found a couple perfect specimens, but they remained elusive - a good reason to go back! We also saw a fair number of families fossil hunting, and it was nice to see lots of people getting into the hobby at such a lovely environment! I myself found too many echinoids to keep [2], specifically specimens of the heart urchin Lovenia woodsii (not to be confused with its cousin, Lovenia forbesi

    Modern or fossil sand dollars?

    I ran across these in a thrift store for a hot buck, so I grabbed them up. It's five sand dollars. One is a little different the others. Are any of these fossil? They seem very clean to be fossil, so I suspect they are modern. Can anyone confirm? Thanks! Edit : the backs are very clean like the fronts.
  7. Return to the Badlands of North Texas At long last, rain graced the lands of North Texas this past week. For many of us, that meant it was time to finally crawl out of bed and beat the crowd to that one particular site desperately needing a refresh. In my case, I set on my way to explore a newer spot in the Grayson Marl while the ground was still nice and muddy. I'd been to this place once before, but it had already been thoroughly picked over. It's a popular site, but even then, it managed to pull through and produce some fine specimens for me to take home. With that in mind, I su

    Goniophorus scotti

    From the album: Duck Creek Formation

    Goniophorus scotti, Tarrant Co. Albian, Cretaceous Apr, 2023 Scoped out my first Duck Creek site that wasn't all the way up in Texoma. I was surprised to find it had a micromorph zone complete with pyritic ammonites and this tiny echinoid. Fingers crossed it might have some sharks teeth too.
  9. Every time I begin a new trip report here on the forum I feel like I need to apologize for how long it's been since my last one. Because although I haven't written anything up since October, I've actually been on more fossil hunting trips in the last few months than in the entirety of last year. This is mostly the result of finally getting a car again back in August after spending the back half of 2021 and almost all of 2022 without one. In fact, I've made so many trips I haven't actually given myself enough time to write up a report about the last one I've undertaken before I'm b
  10. I found this Coenholectypus echinoid in the Mainstreet Limestone in Fort Worth, Texas. Unlike the heart-shaped echinoid that I've found in other formations, these type echinoids' tests appear to have fossilized into a dark crystalline mineral. I'm not quite sure what mineral this is, and hope that it doesn't react to acids so that it can be acid prepped. It can be hard to see in the image, but on the edge of the fractured test you can see that it's made of a dark mineral with a reflective shimmer. I'm not sure if it is just calcite with impurities to make it that color, but of the 5 specimens
  11. Are there any recommendations on where I can donate large quantities of common fossils in the DFW area of Texas? I mostly have ammonites and echinoids and, while they're quite common, I don't want them to all go to waste. The Fort Worth Zoo has a new "Texas Nature Traders" that acts as a museum where trade in nature items, such as fossils, from Texas in exchange for other items traded in. The only problem is that they limit to 4 items, with a collection of 5 similar items counting as 1 item. I'll contact my old elementary teacher and see if she, or any other teachers there, would like any for

    Hemiaster beecheri

    From the album: Ozan Formation

    Hemiaster beecheri, Travis Co. Campanian, Cretaceous Oct, 2022 Urchins are hard to come by in the Ozan, so these are a special find. They are flattened and composed of shale, making them extremely fragile. No chance of finding one in the gravel beds.
