A genuine Eocene fossil fish from one of the world's most celebrated palaeontological formations.
Knightia alta inhabited the vast freshwater lakes of Eocene North America approximately 33.9–56 million years ago. Taxonomically allied to herring and sardines, these schooling fish fed on algae, diatoms, insects, and occasionally smaller fish. They are characterised by heavy scales, small conical teeth, and distinctive rows of dorsal and ventral scutes running from behind the head to the medial fins. Among the most abundant vertebrate fossils on Earth, Knightia are nonetheless prized for their remarkable preservation and the immediate visual impact they bring to any natural history collection.
The Green River Formation of Wyoming, USA, is globally renowned for the exceptional quality of its fish fossils, preserved in fine-grained oil shale that captures skeletal anatomy in extraordinary detail.
Please note: these are genuine fossils. It is common for preparers to apply a brown protective stain to the matrix and to lightly reconstruct fin positions to contextualise the specimen. Each piece is selected from stock within the stated size range — colour, matrix character, and preservation will vary as with any natural specimen. The image shown is representative only.

I’ve probably ordered jewel beetle elytra from at least 15 different companies by now so when it comes to quality elytra I know my stuff and the quality that I just received from ArtButterflies is truly excellent. I would say that the average size from the 1,000 elytra package that I received is slightly larger than average, it’s a good mix of sizes. The shipping was also prompt considering that they are located in the UK and I live in Michigan. It took exactly 10 days to receive my order. If I ever need more jewel beetle elytra I will definitely buy from ArtButterflies again. Thank you!
Beautiful, and cute. Was packaged well!
I was kinda bummed out that I got all beetles instead of the mixed specimens I ordered so I messaged the seller and they are making it right. Ill definitely be coming back to this seller in the near future 😁
Great specimens as always!!! My favorite local supplier

I've ordered from this company many times, always great communication and quality. This time there was an issue with the package being opened and tampered with while in transit (no fault to the shop). Joseph quickly made things right and offered to re-ship the missing items.
