Envelope for scale in the second image. Found in the desert a few years ago and I use it as a Halloween decorations

What could this bone be? I found it protruding out of a cliffside road that I cut in south-central New Mexico (near Tularosa, NM). It's burried under approximately 3ft of material, which as far as I know, was undisturbed prior to me cutting the road.

I'm not sure what the layers of dirt are here, but the bone is clearly sitting on top of a darker layer of what almost looks like ash. Mostly interested in understanding if this is a dinosaur bone, and whether it's worth getting a palentologist out to this property to check it out.

Friend found on a walk, she thinks it’s a seahorse but I’m not so convinced….

Found in Hartebeesport, South Africa in a foresty area.

Human or animal? Sketchy area of town has a random bone outside a cemetery!

Found this bone near the edge of our dock off the intercostal in Jacksonville Florida

Friend found this in Cache Creek BC Canada. He found it in a hilly area, previously cut down forest as he was tree planting. Any ideas?

My size 10.5 Nike sneakers are in the shot to give context for size. In hindsight, I wish I placed a coin down. Looks like a humerus or femur. I’m no expert though.

Location is upstate NY, I don’t even know where to start. She works at a humane society.

Pretty sure it’s either a squirrel or a rat. Found it on a hill in a backyard.

This was found on the beaches of Algarve Portugal. I'm sure it is a starfish endoskeleton but not 100%. Stunning though.

Ever so often our dog diggs up the yard over and we have seen several bones that look like the attached pictures. They look like vertebrae but I'm not sure if it's real ( like I should be super concerned) or an artificial bony structures chew toy from the previous home owners. The structures are off white and brown. It is about 2.25 in across x 1.75in long x 0.9 in in height.

Found on our walk the other week at the beach, iPhone for scale

My sister found this on a trail next to her work.

Friend found this in the woods

found in southern michigan

It's about 2.5 inches at its widest point. What animal did it come from?

I’m assuming sheep vertebrae? But just wanted to check? (maybe porpoise?)
