Huge bivalve

[pierre liew]

Found this ABSOLUTE GIANT of a clam or bivalve around flagstaff point wollongong, nsw and it has another medium sized bivalve in it. if anyone knows what it is that would be awesome.

I know some of the inoceramids grew pretty large, but this looks more like it's from the Pleuromyidae to me.

Nice find.

Nice find.

inoceramids tend to be flatter however

Just a style tip: it is preferable to keep the titles shorter and leave the details in the body of the topic post.  

[pierre liew]

 Clamus gigantius        Just kidding.  One awesome clam if you ask me

lol agreed

I just reasearched the geology of the area and found out that the sediments range from the Permian into the Triassic, so Plagiostoma is another possibility.

plagiostoma is more of a roundish bivalve, the one i has is more long but still very interesting

 

[Tidgy's Dad]

I agree. I have some Plagiostoma specimens and they don't look like this fossil.

thats awesome

Pleuromya it is then unless someone else thinks of something better, although I do have a Pholadomya giganteum in my collection which looks somewhat similar to this one. Not all of this genus are so roundish. It's from the Early Jurassic, but they do range back to the Triassic. It's 11cm. long.

if you look close to my fossil were the shell starts and like curves the there are very visible lines and ive found multiple fossils of this clam and they all have the very identifiable lines where the muscle of the bivalve would be and your shell fossil doesnt seem to have it

Thanks. Unfortunately I can't find any photos of this species in the Triassic, but it could be possible that it has similar "lines" to yours. Even within a species there can be quite a variability in the ornamentation. At least the shape is similar.

everyone i just found out something really cool

these 2 fossil were found 2 months apart from each other and i thought the other smaller fossil was of a plant then i realised it was the lower shell of the huge bivalve and they still fit perfectly
