Dinosaur egg?

[0dinofthenorth]

I found this rock in my back garden, in the gravel where you can find devils toenails. Is this dinosaur eggshell? I thought it was when I found it, but I am not sure. Can anyone help me?

edit: 2.7 cm long!

Here are some pictures, I hope they help. My camera can't get any closer up pictures, sorry.
