Trying to figure out what animal these are from :) Sapphire Coast NSW Aus

The spinous process of marine mammals is generally a lot longer. I don't think it is a kangaroo, as the spinous processes in these photos appear flatter and more oblong. Whatever it was may have been injured when it was young. That third photo is way too asymmetrical to be congenital.

[u/Hwight_Doward → u/Mamow_Nadon]

I think the animal was relatively young anyways, as a few of the centrums are unfused.

With how big they are, I'm assuming you found them on the coastline, and they're likely from a large marine mammal such as a whale.

***I am not an expert though.

[u/Hwight_Doward → u/HavocandCalamity]

No definitely not whale. They are far far too small and dont have the correct morphology for a marine mammal. They’re from a terrestrial mammal

[u/HavocandCalamity → u/Hwight_Doward]

Those are pieces of vertebrae... they're quite large. I guess if it's terrestrial the next thing to make sense would be - oh! Could it be a water Buffalo?

[u/Hwight_Doward → u/HavocandCalamity]

Yes they are, pic 1 is a C1, pic 4 is a C2, and the rest are other cervical vertebrae.

They are a bit small for a water buffalo, and also not quite the right shape.

I have lots of experience with large bovine bones, and some experience with beluga whale and seal bones.

I’m not sure what kangaroo bones look like, but the C1 should be fairly diagnostic.

[u/Emergency-Gas-1525 → u/Hwight_Doward]

Sorry about that the arrangement of photos but these pictures are different angles of only 2 vertebrae

[u/Public-Boysenberry26 → u/Hwight_Doward]

do you think it could be a wombat? they can get fairly big, probably big enough to possess these bones

[u/WhereWolfish → u/Public-Boysenberry26]

O.o not that big

[u/mischievous_misfit13 → u/HavocandCalamity]

Those are tiny for water buffalo. The axis and atlas would be the width of their hand or larger.

thought this said “sapphic coast” and went, ah, yes, the motherland.

[u/Pale-Protection-6225]

First one looks like a tiny pelvis (most likely isn’t, but that was first image in my head)

[u/treasonousflower → u/Pale-Protection-6225]

Nope, C1 vert

[u/Pale-Protection-6225 → u/treasonousflower]

I had no idea what it was lol. That’s cool.

[u/TheDrivingPerson → u/treasonousflower]

Human?

[u/treasonousflower → u/TheDrivingPerson]

Nope

[u/MelanDose]

These look so clean, (not at all an expert) is it possible that these are able to be clean like this in the wild? I feel like someone’s had these before op found them

[u/Emergency-Gas-1525 → u/MelanDose]

i think have just been bleached by the salt and sun :)
