Identification please

[botanica]

Can anybody tell me which tree this is the fruit of? I found it on the ground in my local park.

This is not a photograph, I scanned it. It is round and was a light green colour when I found it.

As I said in my post, this is a scan, and doesn't show the shape very well.

It is round, with a diameter of 6 cms. There are 8 of the "nuts" in it.

I'll take it outside and see if I can crack the "nuts" open. Will report findings later.

I managed to extricate one of the "nuts" from the fruit. The "nut" was very firmly attached, and it required quite a bit of effort to remove it. It certainly looks like a small hazelnut.

I split the nut with a hammer blow. The shell is very thick, about 3 times the thickness of a normal hazel. Inside was a brown fibrous substance, but no nut.

So, the question remains, what is it???

I don't think so, it doesn't look diseased. We've had some strong winds here lately, and I think they may have blown them down before they were ripe.

Certainly looks like Cob Nuts. Are there other trees nearby as Cob Nuts seem to need a pollinator rather like apples. Wonder if it was the hot dry weather we had for part of the summer which made the nuts fail to swell.
