I was knocked out (figuratively) by this little nodule as soon as its finder and preparator posted it. It now sits prominently in my belemnite display cupboard. Belemnites are my main interest which is the official reason I wanted it, but for some specimens it's just love at first sight. It's a Nannobelus acutus (I think - it's not always straightforwards...). They're scarce in this subzone locally, and only very rarely crop up in classic Sinemurian ammonite nodules from Dorset. In fact, I know of only one other but I'm sure there are more out there. (At other levels, and elsewhere, it's a common belemnite.) The ammonites are mostly Cymbites sp. (little, sub-spherical things), with one Asteroceras cf. margaritoides visible (there's another hiding under the belemnite). I think it took vision to decide to prep this - cracked open, you'd just see common little ammonites and a broken belemnite which a lot of people might not bother with, but it's turned into one of the most aesthetic specimens in my collection. Lower Jurassic, Black Ven Mudstone Member. Obtusum Zone, Stellare Subzone, Charmouth, Dorset, UK Nannobelus: 4.5cm Asteroceras: 1.8cm Cymbites: 1cm down to 2mm - I love the hollowed apertures!

Found this yesterday. Only went out to test my new estwing. I saw no sign of an ammonite on the outside of the Rock. Just had that shape about it. The right colour, the layers. One firm hit and it just popped. I made that noise. You know the one when a fossil catches you off guard. Decided it was worthy of a prep. Paddy Howe in Lyme Regis did it for me. Very good job and even better price. Anyway, here's a few pics.

Are Asteroceras Common In The U.s. Central Texas Region?
ideal214 posted a topic in Questions & Answers
I am new to the site and had a question on asteroceras and how common they are to find in Texas or the U.S. for that matter. Any information would be greatly appreciated, thank you. I attached a few images of the fist few I've found still have a huge bucket to go through.- 13 replies
