Hello, A buddy recently gave me this snazzy trilobite, but unfortunately the label on the back said 'Metacanthina', which I think is wrong.. Is this a New York Bellacartwrightia? Cheers, Marc

Entry includes detail of eye lenses. One of the defining characteristics of this particular species, apart from the impressive eyes, is the convex nature of the anterior portion of the glabella.

Hi all, During my trip to Resteigne, I namely found this coral. Here is the location info: Resteigne quarry, Belgium Jemelle Formation (mostly) Eifelian, middle Devonian; ~ 390 mya Any possibility to name the species do you think? Thanks in advance for your replies! Max

Hi all, In my trip to Resteigne, I was hoping to find a trilobite. Though that didn't end up too well, I think I did find something like the "hint" of a trilobite. A tiny piece of trilo armor. But when I say tiny, I really mean TINY. It's really just a fragment. The trilobit of trilobits. Location info: Resteigne quarry, Belgium Jemelle Formation (mostly) Eifelian, middle Devonian; ~ 390 mya Here are some pictures of where I think the piece is. It's the slightly darker part, the really shiny black thing in front, with the tiny little bumps. The last picture, I made it a bit wet, maybe this helps people visualize it better (it does help me). So, is it indeed a small trilobit? I'm pretty sure it is. But I am well aware that there isn't enough of it preserved to determine a species. Looking forward to your answers! Max

Hi all, During my trip to the quarry of Resteigne, I namely found this brachiopod. Is this a Sieberella sp (as proposed by Roger @Ludwigia)? Because the fact that it is asymmetrical makes me want to incline to bivalve... But I'm not sure what kind of bivalve it would be then. Location info: Resteigne quarry, Belgium Jemelle Formation (mostly) Eifelian, middle Devonian; ~ 390 mya Thanks in advance for your replies! Max

Hi all, On my trip to Resteigne last weekend, I namely found this thing. At first I thought it was some kind of coral, but others are having their doubts. So now me too! Here is the location info: Resteigne quarry, Belgium Jemelle Formation (mostly) Eifelian, middle Devonian; ~ 390 mya I started prepping it a little bit, and noticed that this matrix was a little bit softer than the other matrix... So maybe this is from another formation. If I remember correctly, this was one of the few finds from the second level (the levels of the quarry are ground, 1st, 2nd and 3rd level. So maybe the different levels indicate a different formation), opposed to the majority of other finds which were from the first level (and have a much harder matrix). So. What do you think it is? Looking forward to your answers! Max

Seemed like a good time to get this up. It was found in Little Brassua lake in north western Maine (low water, shallow lake). It is from glacial material that is most likely lower Devonian marine sediments.

Old time Devonian coral specimen from Devonshire, UK. Frechastraea
TqB posted a topic in Member Collections
Specimens of corals from the Devonian limestones of Devonshire in England are hard to come by nowadays - this is one I've just bought and repolished. It's likely to be a 19th century sample from when the quarries and marble trade were flourishing - many such pieces were sold then as scientific specimens, and many more were used decoratively. Frechastraea sp. , Givetian/lower Frasnian, Torquay area. The brass scale bar is 1cm long.

Before having to teach, I decided to take a small walk along the Thames River that runs through our campus. The river runs a course of about 170 miles, and was extremely high after very heavy rains and high temperatures that melted a great deal of snow. Since then, the river levels have receded significantly, leaving large stretches of sand and transported materials. I didn't plan on doing any collecting, but where there are rocks... So these are two snaps of the bank. The deposited material went on for some distance.

Hi everyone! So Friday morning, after a few enjoyable days of skiing in Switzerland with my dad, we decided to leave the village because the weather was really becoming horrible for any further skiing (especially for a beginner like me!). I had done a little bit of research as to what fossil locations we could visit on the way back home, and eventually Kevin @Manticocerasman very kindly pointed me towards the site of Resteigne in Belgium! A (no-longer in use) quarry known for its Devonian brachiopods, corals, crinoids and sometimes trilobites. Which was a fantastic opportunity for me, because in my so far 7 years of fossil hunting I had never been in a quarry or hunted for trilobites!!! So seizing the opportunity, we booked a Bed & Breakfast in the small village of Resteigne. We arrived late that evening after a long and annoying road, but luckily the hosts were still up and warmly welcomed us. The man knew quite some things about the great geology of the area, and told us that apparently this region was now a Geopark of the UNESCO! (To avoid any confusion, we are allowed to collect fossils here without any problems. It is not like the national parks where it is forbidden to take things out). He sometimes found some fossils himself when he was going out on walks. After a good night sleep and a delicious breakfast, we set out to the quarry.
