The Chondricthyans (including the sharks and rays) have been around and keeping the ocean's ecosystems healthy for about 420 Million Years. Today, in celebration of this, I've decided to do a little fun post and list the eight times in Earth's history truly massive chondricthyans have emerged. Hope you all enjoy!!! The First is the Devonian, where there is at least one confirmed fossil (CMNH 5238) of a large currently unnamed Ctenacanthiform shark that reached lengths of 4.2-5 meters (13-16 feet) in length. https://www.mdpi.com/1424-2818/15/3/318 The -
I was able to acquire a nice Giant Thresher (Alopias Grandis, non-serrated form) that came from Lee Creek (Aurora, NC). It's the third in my collection. I'm curious to know how rare/uncommon they are from that location. Giant Thresher shark teeth seem to be found with some regularity in South Carolina, although they be from the Oligocene. Giant threshers are also found in Maryland along Calvert Cliffs (Miocene). I've seen a few other Giant Threshers from Lee Creek in other people's collections and have heard about a few others. Curious to know, especially from some of the long-

Any day out on the river is a great day but today was something special, plentiful teeth and a couple of rarities! My wife started the day off right by finding a symphyseal cow shark tooth, I still can't hardly believe that she found it! Later on I stepped over a log to find a Meg leaning up against another log. Later on in the day, my daughters were hunting together and when I got home and checked out what they found, there was an Alopias grandis there! I finished the day off by spying a 2 1/2" Mako sitting high and dry...I couldn't ask for a better day on the river with my family!

Of all the teeth I've seen come out of Lee Creek (Aurora) over the years when it was open to collecting, I never saw a Giant Thresher shark tooth (Alopias grandis) be found. I know there are pics of a couple on elasmo.com, and recently I saw online (FB) where a young child actually found one in one of the spoil piles in front of the museum. I'm sure more have been found over all the years in Lee Creek, quite possibly with some folks not really knowing what they were. A good friend of mine found one at Calvert Cliffs many many years ago, before I had ever heard of them. I was at the beach t

Here are a few photos of an Alopias grandis (a little over 1 1/4 inches), I found yesterday morning on the Potomac River, VA side. It was my very first find of the day, after I stepped on it, and it is the first one I've ever found in 10 years of collecting/hunting. This one has serrations down both sides, though they are a little worn, which makes it even more special. It was a gorgeous weekend hunting and collecting along the Pamunkey on Saturday and Potomac on Sunday, despite the huge thunder storm at noon on Saturday that dumped 2 inches of rain in 45 minutes which equaled 50 gallons of

It has very minute serrations as well.
