Silurian Eurypterus fossil has apparent symmetrical structures in Dorsal Cephalothorax
Biotalker posted a topic in General Fossil Discussion
I was fascinated by this eurypterid fragment from Ukraine because it has a rough symmetrical pattern on the dorsal surface of the cephalothorax. There is a midline structure with apparent tracts leading to the eyes and perhaps other structures (like downwards toward the abdomen). It doesn’t look like ventral appendages of the cephalothorax projecting dorsally. This has the appearance of some internal structure, fossilized with perhaps some part of the dorsal exoskeleton removed. While very unlikely, the tracts toward the eyes might lend some support an interpretation of a neural or neural structural component. This may very well be an artifact or perhaps someone has another explanation. The lighter two pictures have a light source from above while the darker three have a light source from the side to highlight the contours.

Fossil shark teeth from Ukraine - What formation?
bthemoose posted a topic in General Fossil Discussion
I acquired some Paleogene fossil shark teeth from a Ukrainian fossil hunter/collector and was wondering if anyone here might know what formations these may have come from. They were found on an island in the Dnieper River near/just south of Kyiv. The collector didn't know the specific formation and described them as coming from sand alluvium. From what I can tell, these appear to all be Eocene species, though not being familiar with the local geology, I can't rule out Paleocene for the Otodus obliquus tooth at least. Any ID corrections are of course welcome as well! Otodus obliquus Hexanchus agassizi Jaekelotodus trigonalis Otodus aksuaticus or O. auriculatus

Rovno Amber (Mezhigorje Fm., 33.9-28.1 Ma)

From the album: Fossil Amber and Copal: Worldwide Localities
Two pieces, roughly weighing 7 and 4 grams respectively. Both are mined from the Rivne region of Ukraine's Rivne Oblast, and had a little to no oxidized layer, in comparison to amber mined from the nearby (roughly 50 km) Klesiv Deposit.© Kaegen Lau

Rovno Amber (Mezhigorje Fm., 33.9-28.1 Ma)
Barrelcactusaddict posted a gallery image in Member Collections
From the album: Fossil Amber and Copal: Worldwide Localities
Roughly 12g specimen of amber mined from the Klesiv Deposit of the Rivne region in the Rivne Oblast of Ukraine. It was originally coated in a 2mm red oxidized crust, typical of this locality. It is believed that the presence of this crust is an indicator that amber from this particular locality underwent little to no re-deposition throughout its diagenesis, and oddly contains the majority of described insect-included Rovno material.© Kaegen Lau

Rovno Amber (Mezhigorje Fm., 33.9-28.1 Ma)

From the album: Fossil Amber and Copal: Worldwide Localities
83.8g raw amber mined from the Rivne region in Ukraine. The "eye hole" was likely formed when the organic matter (i.e., tree branch) the resin encased, was likely dissolved/washed away during the resin's diagenesis and redeposition (Baltic and most Rovno material is generally believed to have been redeposited).© Kaegen Lau
