I would love to learn from some of you regarding what species of nautiloids these are (maybe multiple species). They’re different than the larger ones I find more often in similar areas and I like the pattern detail visible on some of them. They almost always have a very distinct curve at the outer edge. These are mostly from 2 spots in burleson TX. The unusual nautiloid with lots of details visible and crystallized (looks brown in the photo) on the inside was from a different spot (maybe Fort Worth formation?) where I find mortoniceras ammonites.

Hi, Just wanted to share my excitement at finally getting a chance to own a genuine lower lias ammonite from the infamous (now sadly closed/filled in) ironstone quarry in Scunthorpe (United Kingdom,Lincolnshire). The fossils found within this locality are mostly preserved in pure calcite and have a range of colours which include stunning/natural pinks and greens. It's due to arrive tomorrow! but I feel so privileged and lucky to grab one and also from a highly revered/professional prepper in the United Kingdom! : http://www.yorkshirecoastfossils.co.uk/scunthorpe_fossils.htm It's only a small specimen (Aegasteroceras sp) but still stunningly beautiful! Scunthorpe ammonites are among the most beautiful in the world (in my opinion) and if you can grab one, grab one whilst they are still within price range for most people because like all things they will go up in value as the years go by due to the quarry being closed. (As it hasn't arrived yet this photo isn't mine! and is property of "Yorkshire coast fossils", but sharing to share my excitement.)
