Plan B - Hit The Ditches

Recommended Posts

Well my fossil hunting day yesterday was cut short when some engine trouble on the boat meant my mission changed from looking for teeth to trying to drop the boat off at the marine shop before they closed. So rather than sitting around the house today and think about how much the repair bill is going to be, I hit the ditches. You know, as long as the expectations are not too high, it is fun walking the ditches even if the finds are usually a 1/10th of the size (or even 1/100th of the size) of my usual river finds. Even though the particular spots I hit had several foot prints indicating I was probably the 10th or so to walk the ditch since the last rain, the finds where still plentiful, just small.

Those are great! I'm getting to where I love the small teeth that we find around here more than I do the bigger ones.

Fossils are simply one of the coolest things on earth--discovering them is just marvelous! Makes you all giddy inside!

Thanks guys. The thresher was my favorite as well. All I saw was the little chubby root sticking out of the mud. These guys are pretty hard to find due to their small size.

Nice finds! Reminds me of Lee Creek material...What is the ID on the tooth in the 10th photo? I think it also shows up in 14 and 15 also.

Cool finds! The only find in ditches here is algae and a possible bilvave. Thanks for sharing!

Good questoin Fossilz. I believe it is an extinct sharpnose shark, Physogaleus secundus, but I am open to being corrected if anyone else knows a better id.

Awesome. I have a bunch of those that were in need of an ID. Thanks.

A Bunch?!

They look a lot like hammerhead as well, both are tiny and I believe inhabited similar timelines and ranges.

Yes, I realize that they are VERY similar to the hammerhead shark. The more posterior you go in the jaw, the harder it is to differentiate between the two.

Nice haul! I'm still lookin' for my first tooth up here, but crab concretions will suffice in the interim.

If these teeth are Oligocene, I would say it is a safe bet that these teeth are Carcharhinus gibbesi. You can do a Google search for "Late Oligocene sharks and rays from the Chandler Bridge Formation" and you will be able to access a pdf. where C. gibbesi is shown in figure 5.

Nice teeth. The preservation is very good.

I think you may be right Al Dente. I found another article that adds a third similar tooth, Abdounia recticona. The article also talks about how to tell the difference between recticona and gibbesi, but the drawn illustrations are not nearly as helpful as pictures would be. I wish the Chandler Bridge Formation article you referenced showd the lingual views. Thanks for the help.
