Doing work in the woods and found these two. Doesn’t seem to be anything else nearby. Any ideas?

I saw this peeking out of the dirt and dug it up. Rinsed it with the hose. Feels like bone but I haven't tried to break a piece off. Only other thing I thought of was plaster.

Measurements: 2.5 x 5 inches

What is it(if anything)? I'd appreciate any help.

Found in a south Louisiana lake. Either very large alligator or fossil. Not sure how to tell.

Alberta, Canada. Found near a river

Found on the south east coast of England about 5/7 cm wide

Found on Sanibel Island Florida, in the surf of a small sand bar, ocean side. It is approximately 3-3.5” long.

I found this skull on a beach of the South Island New Zealand. It also has farm paddocks bordering it.

Found under a chair on a Pennsylvania patio

found about 40 bones in a two foot square no skulls yet but wondering what we are digging up, thanks.

(white squares on the mat are 2.5cm square)

My daughter found this on the beach, off lake erie. Is this a bone? feels too light to be a rock

Smoothed by time in the waves. Any ideas what it might be?

I realized I provided no scale, so it’s the size of a large adult female hand.

Would love to know an approx age as it’s nearly petrified, as well as an identification.

Seems to be a rib bone but does anyone know?!

Smoothed by time in the waves. Any ideas what it might be?

really curious what this is! I've got no clue, but maybe a bone from a deer or other farm animal? those wash up along here often enough I suppose, but I've never seen such a thick but fairly short bone here before

This bone keeps showing up during my walks, but it's finally flesh-free. I'm still unsure what part (skull?) of what mammal (?) it belongs to. There are many farms around but also deer, coyotes and moose.
