A nice Dictyonema flabelliforme dendroid graptolite from Oslo Fields in Norway. It's Tremadoc, Lower Ordovician in age and is thus maybe around 480 mya. Another angle :

Permian Reptiliomorphs Discosauriscus
Lucid_Bot posted a topic in Is It Real? How to Recognize Fossil Fabrications
Howdy! I'm looking to purchase these plates of Discosauriscus from the Permian of Moravia, Czech Republic. They are from the limnic deposits. There is supposedly no repair or restoration. Thank you.

A rangeomorph holdfast trace fossil from the Ediacara formation, Rawnsley quartzite of the Flinders Range, South Australia. This specimen is Medusina mawsoni, so called because it was until recently thought to be a jellyfish, but is now believed to be the attachment point of a fractal rangeomorph as Charniodiscus is the point of anchorage for Charnia sp. This one may have been the holdfast point for some species of Rangea. The diameter of the outer circle is 1.5 cm and the fossil is estimated to be 555 million years old.

Hello dear fellow forum members, I just acquired this nice specimen of a carpoid, sold as Dendrocystites barrandei from the Czech republic which I have no reason to doubt. My first carpoid, yay! Fascinating group. I wonder about the starfish-like impression to the right of the carpoid though, is that an early "classic" echinoderm? Best regards, J

Lagynocystis pyramidalis was first described and figured by Barrande 1887 under the name Anomalocystites pyramidalis. Taxonomy from Parsley, 2000. Lagynocystis pyramidalis (Barrande) from the marine Lower Ordovician of Bohemia, has features which suggest that it is ancestral, or nearly so, to living cephalochordates such as amphioxus (Branchiostoma). Diagnosis from Parsley 2000, p. 258: "Ankyroid with asymmetrical theca. M‘l—M'5 well developed: MI—M3 shortened and reduced in size: M4 and M5 absent; large CS plate. M‘5 protuberant, hollow. Sutures with M’4 and in some specimens narrowly sutured with M'3 but not flexibly articulated. Superior face with distally overlapping platelets that wrap around onto inferior face near posterior ends. Proximal aulacophore with multiplated meres; styloid with four or five denticulate cups; distal aulacophore atypically long with elongate ossicles and tall rectangular cover plates."

Originally the fish was described by Agassiz in 1833 under the name Palaeoniscus vratislaviensis. Taxonomy from Štamberg 2021. Diagnosis of Paramblypterus vratislaviensis from Štamberg 2021, p. 77:”. Small fish usually ranging from 100 to 120 mm, exceptionally to 150 mm. The frontal is 3.5 times longer than wide and 2.5 times longer than the length of the parietal. The anterior margin of the frontal is concave medially, interfrontal suture only slightly undulated and without folds, the sculpture on the frontal consists of ridges parallel with the posterior margin of the bone. The dermosphenotic is narrow, elongated anteroposteriorly. The dermopterotic, with lateral process but without posterior process, is narrower anteriorly than posteriorly. The infraorbital superior, dermosphenotic and supraorbital anterior form the dorsal edge of the orbit. The maxilla has a short and high maxillary plate which is convex dorsally, the length/height ratio of the maxillary plate is 1 or less than 1. The operculum is oblong in shape, 1.4 times deeper than it is long. The scales on the anterior part of the body bear fine ridges extending posteriorly to the denticles. Denticulation decreases on the scales in the posterior direction and the last denticulate scale appears in the 13th scale row. A field of small scales occurs along the base of the anal and dorsal fins.” Line drawing from Štamberg 2021, p. 82: Paramblypterus vratislaviensis (Agassiz, 1833). a: restoration of the body in lateral view, scale bar 10 mm.

Ellipsocephalus hoffi is a common trilobite mainly from central Europe. The slab shows several Ellipsocephalus remnants. Taxonomy according to Fossilworks.org.

Does anyone know what amphibian this is? I acquired it as a Letoverpeton moravicum from the Bacov Formation of Moravia, Czech Republic As I understand, Letoverpeton was synonymized with Discosauricus. However, this doesn't look like the typical Discosauricus to me. I am not familiar with amphibians from the Czech Republic, so I would appreciate any help in identifying them, thank you

Where in Prague, Czech Republic, can I find/buy fossils?
FossilizedFanatic posted a topic in Questions & Answers
Hello, someone I know is going to Prague soon. He asked me if I knew any spots in/near Prague for hunting for fossils. I didn't know any, and a quick internet search didn't give me any more information. I was wondering if any of the people on here know what it means Thanks in advance! -

Hi all fossil lovers, I am not just an amateur collector but absolute newbie to this field. I just started my new interest and I am glad I found your forum with so much interesting information. You guys have a great forum over here and looks like lots of interesting people. Great work I enjoy traveling, mountaineering, diving and basically anything what involves outdoors. This year I want to go and start fossil hunting, have to wait couple of months because right now we have about a meter of snow over here. Hope luck is on my side and I will have some pics of my own finds to post here soon. Please if my spelling gets doggie take it easy with me after all English is not my first language Thanks

Hi guys! Yesterday I visited Koneprusy (Devon) in the Czech Republic and found some fossils. It was first time finding fossils But I´m not sure about these two.. I think the first one is crinoid (photo #1). Second one looks like a fossil wood (photos #2-4) to me, but I´ve never found one so it might be just some kind of mineral. I don´t know. Thanks for your help P.S.: Ruller is in centimeters.
