Not quite sure if this piece of fish jaw is X-fish or Pachyrhizodus. What do y'all think? Found in the Ozan formation of Fannin County, Texas.

Good afternoon to all. A colleague and I were doing some exploring in a creek bottom on our jobsite located in Fannin County, Texas. The creek we were walking in drains into the North Sulphur River. As we were walking we noticed a large bone sticking out of the creek bank. We decided to grab a couple of shovels and do a little more excavating. We came across multiple bones. As you may see in one of the pictures, we had to do a little digging in order to reach much of the bones, they definitely weren't just lying in the creek bank. I will upload more pictures with measurements. I kinda want to gauge if we stumbled across actual fossils, and if so we were hoping for some sort of inclination of what we may have found. The coordinates for the find are 33.4122,-96.0804. We were at least 15 feet below the grade of the jobsite in the creek.

From the DPS Facebook page: The Upper Trinity Regional Water District has received a permit from the US Army Corps of Engineers to construct Lake Ralph Hall on North Sulphur River. The Fannin County Leader February 6 at 1:41 PM · UTRWD Receives Federal Permit to Build Lake Ralph Hall Board of Directors Received USACE’s Section 404 Clean Water Act Permit LEWISVILLE, TX – Feb. 6, 2020: The U.S. Army Corps of Engineers (USACE) has issued a Section 404 Clean Water Act Permit to the Upper Trinity Regional Water District (UTRWD) for Lake Ralph Hall, one of the first major reservoirs to be built in Texas in 30 years. This is the final federal permit required to construct the lake. The Texas Commission on Environmental Quality granted UTRWD a water rights permit for the proposed reservoir in December 2013. Named after longtime U.S. Congressman Ralph Hall, the reservoir will be located in southeast Fannin County on the North Sulphur River and will provide essential water to North Texans. “After nearly 15 years of working with USACE, we are excited to receive this permit as it moves us one step closer to building this critically important new reservoir to meet the water needs of our growing communities,” said Larry N. Patterson, UTRWD Executive Director. “After many technical studies and extensive field investigations by both federal and state agencies, the Environmental Impact Statement was completed leading to USACE’s Record of Decision for Lake Ralph Hall. This is the culmination of a lot of hard work by UTRWD staff, its consultants, USACE, collaborating agencies and our local partners in Ladonia and Fannin County,” Patterson said. UTRWD’s water demand within its growing service area is anticipated to increase nearly threefold over the next 50 years, additional water supplies are needed to meet this anticipated future demand. Once complete and fully operational, Lake Ralph Hall will provide residents and business of UTRWD’s service area and southeast Fannin County an additional 54 million gallons per day (MGD) of raw water. “Design of the Leon Hurse Dam is near completion and construction is expected to begin later this year in order to have the new lake in operation by 2025,” states Mr. Patterson. “Lake Ralph Hall will provide a reliable water supply for many generations.” “We appreciate our Members and Customers demonstrated support throughout the permitting process and the diligent effort by USACE to finalize the studies and issue the permit,” Mr. Patterson continued. Here are a few facts about Lake Ralph Hall: • USACE’s Environmental Impact Statement confirmed that the North Sulphur River near the City of Ladonia is a good reservoir site - - limited wetlands, no oil or gas wells or electric transmission lines. • Will inundate about 7,600 acres (similar in size to Grapevine Lake) but will yield about 30% more water because of greater rainfall in the Sulphur River Basin. • Helps address severe erosion on the North Sulphur River and will provide a significant aquatic and terrestrial habitat in Fannin County, one that doesn’t exist today. • Pipeline that now delivers UTRWD’s water from Chapman Lake was built with enough capacity to carry the water from Lake Ralph Hall to UTRWD’s service area. • Provides economic benefits to Fannin, Denton, Dallas and Collin Counties. • The Texas Water Development Board’s State Water Implementation Fund for Texas (SWIFT) program will be used to fund the project, estimated cost of $490 million.

I was out at the North Sulfur River on Saturday. I found a number of cool things. This one is a mystery to me, but it seems very rare and pretty neat. I’m not sure it’s even really identifiable as to a class or order, but I thought I’d ask. It needs more prep, but I’m not sure how much more there is to uncover. Above you can see what look like 2 legs hanging down and possibly One on op. Below is the same thing invented. Another pic from a different angle. I can’t get any closer on the small details. I can see the texture of what I believe may be legs on the bottom of pic 1, but they aren’t crustacean legs. I guess they could be antennas, but I’m not sure antennas are segmented like that. If you look at what appears to be an appendage on the top it does have bumps on it. Any thoughts?

Here is another bone from the North Sulfur River that is Pleistocene in age. I found it Saturday. I am not sure what it is or what it is from. It is slender and flat towards the bottom and roundish on joint end, but still a little flattened. My wild guess would be ulna, but it is just a guess. I’d like to know what it is from. Long edge side 1 Long edge side 2 The joint end side 1 pic 3 Joint end side 2 pic 4 Pic 5 looking straight down on joint end Pic 6 This is the other end of the bone.

Yesterday I went hunting in the North Sulfur River in North Texas. Could this be a fragment of a coprolite? Pic 1 and 2 are same pic different lighting. I was trying to bring out the button in the center of what I’m calling the bottom. Pic one brings it out, but it is grainy. Pic 2 you can zoom in better. The center kind of has a pinched button look. # 3 the top. It looks like clam shell fragments possibly. The next 3 are side views. The whole thing is dome shaped. @GeschWhat

Today my husband and I took our first trip to the North Sulphur River at Ladonia, TX. We were able to search for a few hours before the heavy rain moved in. Here are some of the finds that stood out the most to us. We are newbies and would appreciate any help identifying what we have. I will be posting several pictures in this thread. Thank you in advance.

I took a trip out to the North Sulfur River today. These bones were one of my finds from an avalanche that had happened. I believe they are Pleistocene in age. They are not heavily mineralized like the Cretaceous bones found in the river. They are at least partially mineralized though. I have never found and Pleistocene bones. This is the full length of the bone. One end is flatish and the other convex. This is a view from the side. I believe it may be a vertebra. The back side is broken off where spinous process would attach. Side view. Convex End view This is another bone found at same spot a few feet away. I think it is a sacral piece. I have a couple more fragments too, but they do t seen diagnostic. Can anyone tell me what they are from?
