Fossil tooth from a float trip

My family went on a white water tubing trip in Harpers Ferry, WV. The bag fell in the rapids. When we got home the “rock” was in the bag.

Fossil Collector: COHara

Location: Harpers Ferry, West Virginia

Editor’s Note: Given that it was a tubing trip, we are glad that you only pulled this tooth out of the bag. We will resort to an emoticon for that statement :) This is half of what is likely a fossil Carcharodon megalodon shark tooth. Accidentally finding its way into your bag is a remarkable bit of luck. ]

Daily fossil catch

Fishing for fossils yields a crystal conch shell.

Fossil Collector: Alex B.

Location: Florida

[Editor: Beautiful find and an interested method of fossil collecting! Florida is well-noted for calcite crystal encrusted shell fossil like this whelk or conch. Very interesting both as a fossil an for display. Similar fossil are found more conventionally at the Drum Point Crystal Mine and throughout the state.]

Mammal fossil

I was walking on the beach looking for seashells, and saw this laying on the beach.

Measuring the fossil

I thought it was some sort of driftwood, but the shape was strange and it looked petrified. I showed it to my boyfriend who said it looked like vertebrae. Because of the color and hardness, we believe it's a fossil. Not sure what kind though!

Fossil Collector: HeathPak

Location: Carolina Beach, North Carolina

[Editor's Note: This mammal fossil looks to be the vertebrae of a seal. The exact age may be difficult to determine unless you were to know the specific geologic formation it came from, but it is likely Miocene which could mean anything from about 5-20 million years.]

5-24 million years old

Fossil mammal tooth on a shell for scale.

Beach combing can lead to some surprising results.

Location: Miramar beach, Portugal

[Editor's Note: This is a mammal tooth and our first impression is that this looks like a tapir tooth. Having said that, we're not especially knowledgeable Ice Age Portugal. Can someone else add the this? Please leave a comment.]

Possible crinoid fossil?

Fossil was found on western shoreline of Lake Michigan two miles north of Glen Arbor, MI.

Possible horn coral fossil?

It was mixed in with a variety of stones at the edge of the surf. The circular feature immediately caught my eye.

Fossil Collector: Scott M.

Location: Glen Arbor, Michigan

[Editor's note: Hmm...the top picture certainly looks like the texture of a crinoid fossil. The second picture could be the cross section of a crinoid, but also looks similar to the base of a horn coral. Any thoughts from Michigan collectors?]
