Is this a rock or an egg?

[MaraFossil]

Hello all!

 

I’m new here and extremely new to fossils! Today, we went fossil hunting in Walton-on-the-Naze in Essex, England. It’s not far from where we live and is known to be one of the best places in the UK for fossils (particularly the teeth of megalodoms).

 

Anyhow, I found this item and wonder if it’s an egg or a rock.

 

It is relatively small, just under 3 inches long. It feels substantial in weight, 137g, and has cracks and pours.

 

Please see the attached photos

 

 

Location information: The fossiliferous clays and sands exposed in The Naze area belong to the London Clay and Red Crag formations, and provide evidence of prehistoric life and conditions 54 million years ago (mya) and c.2.5 mya respectively. Fossils occur commonly throughout both formations attracting international interest since the 19th century.

Sorry not an egg, looks geologic

Could be man made.   You would see eggshell material on eggs

It’s more than likely a flint nodule. Definitely not an egg. Walton is great for bivalves, gastropods, and shark teeth, so keep an eye out for those!

Agreed, a flint nodule. The holed ends are likely to be due to it containing a fossil sponge.

 oh well, the dinosaur egg was fun whilst it lasted. The kids enjoyed the idea. Thanks for all your help in identifying my rock!
