I just went fossil hunting today and found this. Is it a bone or just a rock? If so what is it? It is found in Beaumaris in Victoria. A majority of fossils are 6-5 million years old. I have theories as to what it is if it is a fossil, but I am unsure. I was thinking a an extinct penguin upper wing bone or a Pelagornis shin bone, maybe even a seal metatarsal. This is a link to a list of fossils found in Beaumarishttps://www.bayside.vic.gov.au/sites/default/files/2021-08/beaumaris_fossil_book_museum_victoria.pdf Personally, I am sceptical as to whether it is a bone but my Mum and Dad believe it is.

I am excited to finally announce my first contribution to science! This is a section of dentary/beak of a Pelagornis cf. sandersi from the Ashley Formation in Summerville, South Carolina. This was found in December 2023 and has been donated to the new Charleston Center for Paleontology, where it will reside in their collections. A paper featuring it and other Pelagornis sandersi fossils from the area (which there aren't many of) is in progress. Here it is after prep:

hi from France my first post ..... I've found this scapula (i thought it was?) in a french burdigalien (inferior miocéne) site (Cestas 33 Gironde France) I thought it was from a sea mammal animal , but the very light bone structure make me think that it could be a (very) big bird coracoid bone (like pelagornis?) So your feelings??? (sorry for my poor english..)
