Hi, I found these when I was walking on the beach today (N. Florida). Can anyone tell me what I found?:) The long one is 27cm long and they are both hollow. The other one reminds me of sand dollar but it has a weird shape...

They are probably sand dollars. Some types can be hollow. Most are in fact.
