Last Ramanessin Brook Trip for Summer

[A.C.]

Hey all,

Made two trips to Ramanessin Brook that I have yet to share. The first trip provided much of the same stuff I had already had but did yield me an amazing sawfish rostral tooth. The most recent trip (8/17/21) is where the majority of what I wanted to share was found.

Congratulations! That sawfish rostral is awesome. Other finds are excellent too. Your sand tiger looks more like a goblin tooth. Would need to see it from different angles to be sure. Also, not sure about the croc tooth. It might be, but would need a closer more detailed view to know for sure.

It seems the creek has been good to you!

As Jeffrey P says, the "sand tiger" looks like a Scaphanorhynchus texanus (goblin shark) anterior tooth.  Scaphanorhynchus was a confusing critter, as the teeth differ dramatically according to their position in the mouth.  The anterior teeth are long and slender, without cusps but with prominent striations, so they can resemble sand tigers.  The lateral teeth lack striations (or they are much less obvious), have prominent cusps, and have a broader blade.  These teeth might be confused with Cretalamna without a closer look.  Also there are differences between upper and lower teeth.  Back in the day when shark species were named from single teeth, without accounting for variation due to position, several "species" were named based on Scaphanorhynchus teeth.

That is an amazing Ischyrhiza mira. Especially for where it was found. Thank you for sharing it with us.

Your "bone material" is almost certainly an Enchodus. palatine

Here are some (hopefully) better pictures... any idea what if not croc?

Now that you say it and I look it up I can totally see it! Thanks I was almost certain I would never get an ID on it!

That tooth appears more robust and I believe I detect a cutting edge. Croc teeth tend to be more conical without a cutting edge. Therefore I'm leaning more towards mosasaur. Mosasaur teeth though uncommon, are much more abundant than croc teeth.
