  1. Hello all. I just wanted to share some information about keichousaurus that I found very interesting. Crazyhen recently identified a keich specimen I have as a male. I wondered how he knew that, and did some research. As most of you probably already know, keichousaurus hui was sexually dimorphic! Males can be told apart from females by the proportions and length of the femur and humerus. Males are also often times larger. I included a diagram telling apart the male from the female. A is the female, and B is the male. Thank you all for reading, I enjoyed learning this and hope some of you do as well! https://www.tandfonline.com/doi/abs/10.1671/039.029.0230 https://royalsocietypublishing.org/doi/full/10.1098/rspb.2015.1658
  2. Florida humerus

    I found this today. Not sure exactly what it is from. It is 6" in length.
  3. I hope you all had a good Christmas and are looking forward to the New Year. I thought I’d treat myself to a Christmas fossil this year. It’s an iguanodon humerus (maybe Mantellisaurus now) from the Isle of Wight. The humerus is about 700 mm long, so pretty big and heavy. I got a local blacksmith to make the stand for me and I picked it up today. Regards Nick

  5. Found in South Manatee County in an aggregate pit. Thank you!
  6. Looking for identification for this bone. Possible femur or humerus of a turtle? Found in Manatee County, Florida. Thank you!
  7. Small rodent humerus ? Savannah, Georgia

    Hello, I have what I think is a small humerus from a rodent of some kind ? This is dredge material so it can range from Pliocene to Pleistocene. Was curious if it was possible to determine the type of rodent. I'm assuming it's too small for a capybara type of animal. @MarcoSr does this resemble anything you have seen ? Cheers, Brett
  8. Bird long bones from Uppermost Pleistocene of Lithuania

    Dear Guys, I have collected several interesting bird long bones in the sand dune layers of Varena town, South Lithuania. Judging by the local stratigraphy and history, the sand in varena town is formed in the last glaciation (25- 10 thousand years ago), so there in my bone finds can be some bird genera that do not live in the Baltic Region today. If someone is familiar with ornithology, please take a look and help me to identify bird taxa. Any help will be appreciated! Best Regards Domas At first, I show tibiotarsus fragment of possible big vulture (the largest width in articular part is 2 cm)
  9. Distal end of Left Humerus

    Human? Found in Galveston Bay dredge spoils. Darrow
  10. Bones, bones, bones

    Hello Forum, I picked up a few fossilized bones....two possibly complete and two partials. The gentleman I got them from could only give suggestions as to what the complete bones are - and no idea at all about the partials. I tried grouping the pictures of each together and numbering the group - hopefully this is helpful rather than not. Pic 1: possibly a dinosaur hand or foot bone Pic 2: no idea. Pic 3: possibly a horse humerus. Pic 4: no idea. Locations: Pic 1 - Fort Crittenden Formation, Pics 2 & 4 - possibly either Fort Crittenden Formation or another location in S/E Arizona Pic 3 - Jacksonville Florida. Thank you for any and all assistance.
  11. Help on ID of bone

    So over the Holiday I went shopping in my old town at the Antique stores. Love hitting places like that. You never know what you may find. Well I found an older case of fossils and rocks. They came from a guy in a neighboring town who had the rock, mineral and fossil store. He sold out and these were bought. I will be posting a few in other threads and would love to get names for my collection and knowledge. So. I have no idea of information on this one. Some of you I know will have speculations and that will help narrow down what it is or is not. I believe it is a Humerus bone??? It is 9 inches long. The scale is in inches. It is hard and fossilized. I do wonder about what the cut or groove is on the end. Is that normal or man mad while prepping. If you need any other pics let me know.
  12. Hi, I was out this morning doing some collecting at Bouldnor Cliff (thought I'd mix it up from Hamstead for a change) and came across this distal portion of a mammal humerus lying on a mudflat. I'm regular collector along the north coast and know the vertebrate taxa and stratigraphy like the back of my hand but this humerus is unlike anything I've found before mammal-wise. I noticed straight away that it has a supratrochlear foramen, which from my own knowledge and some online research is a feature often found in canids. Material from amphicyonids like Cynodictis and Amphicyon have been found from the Bouldnor Formation (Rupelian aged, and spans 34.0 - 32.5 mya) but I'm unaware of any canid material, so I was looking to perhaps get a second opinion on whether this is canid, and/or whether the supratrochlear foramen is a reliable indicator of canid/carnivoran material. Any help is much appreciated.
  13. Raptor Arm

    Partial right humerus (upper arm) of an undiscribed Dromaeosaurid. The size is very similar to that of Bambiraptor. This animal was possibly just over a meter long.
  14. Strange mammal bone found

    Dear Guys, I have found one very specific bone fragment which is very hard to me to identify, it is from Late Pleistocene sand layers of Varena town, South Lithuania. The wider part of bone has very strange joint relief and I do not know which animal is this. Please help with ID of this fossil. Best Regards Domas
  15. Mosasaur Humerus?

    Hi everyone. I recently bought this Mosasaur fossil that was labeled as a Tylosaurus Humerus, and i just wanted to check if this is indeed a humerus or another part of a mosasaur because looking at some pictures on the internet of mosasaurs (and Tylosaurs) it could also be a radius. It is 5 and a half inches in length and was collected in the Niobrara Formation in the Smoky Hill Chalk (Kansas). Since i am not an expert on mosasaurs (i am still learning about them) and my knowledge is limited, i was hoping someone who knows about mosasaurs could help out in confirming if this does belong to a Tylosaurus and if it is a humerus or a different part. I do trust the seller i just thought it would be worth posting on the forum to see what others think. Any help would be greatly appreciated.
  16. Possible cave hyena humerus

    Dear Guys, Today I found one very interesting piece of bone, I think it is humerus of big carnivorous mammal like hyena. The size of bone is 10,3 cm length and 6,5 cm in the articular part. If it would be Cave hyena, it would be very rare find, my country belongs to Baltic States, Eastern Europe. The age of sand layers in my area is about 10- 13 thousand years. Please help with ID Best Regards Domas
  17. Fossilized humerus?

    Found this in a pile of river rock here in Kansas. It's heavy like a rock. I'm a newbie so need some help. It looks like a humerus to me and you can even see the different colors that show the marrow. From surfing the web I've seen very similar shapes of fossil humerus of porpoise, whale and alligator. Should I get back to that pile and keep looking?

  20. Bone of Large bird of México

    What opinion do you have, is a large bird jaw or is another structure? It was found in tufa calcareous with river bivalves of the late Pliocene of north of Mexico.
  21. Bison priscus humerus

    From the album Ice Age Europe

    Distal end of the sinister humerus from a Bison priscus (Steppe Bison). From the Mannheim Formation, Middle Würm Interstadial, 58,000-26,000yo. Germany.
  22. I'm fairly certain this is a humerus, but to what? I am a herpetologist and spend a lot of time along rivers. I came across this today as I was searching for frogs, and I decided to hang on to it to ID it. So far, I have been unsuccessful and I assume you guys are way better at this than me. The bone/fossil doesn't feel as heavy as most fossils I have come across, but it is definitely heavier than bone. It is completely black underneath the crispy tan layer shown in the photographs. It was found in an area along the river bank that had recently been washed out due to recent rains. So I'm not certain if it originated high above the bank or in the wet sand. Thank you, Buddy
  23. Humerus Bone? Please Help Id

    I found this interesting bone fragment in my raised garden bed. I think it must have come in one of the bags of cotton burr compost I applied earlier this Spring. I used 2 different brands of compost -- they came from Georgia, Texas and Oklahoma. This bone measures 5.5" long, and 2" wide at the joint end.
  24. A Humerus Trip

    August 15, 2009 It all started on a small, secluded Texas waterway in the Jungle of Gigantism (you know better than to ask), we watched a log submerge with purpose... but, it was no log. Big reptiles were only a hint of the giant to come. Shortly afterward, we pulled into the bank and my friend Dan offered, "you want upstream or downstream?" Words he later said would influence a fossil career. It was 7:45 in the morning. I headed downstream to low gravel ledge. Within a short time, I found an unusual shaped bone, a little over a foot long, wedged into the bank. It turned out to be a limb bone of a giant sloth! It even had gravelly sandstone attached to it. I laid my paddle beside it and continued to search the ledge. Finding nothing else, I thought that I should check out where the ledge dropped into the water...and there it was. A dinner plate-sized dome edged from the steep face, halfway down to the water. To the casual observer, it would seem to be another rock, but the shape resonated in my consciousness - bone...big bone. Sloth bone I returned to the first bone and took a few in situ photos. Dan was working his way back toward the boat about 100 yards away. He hollered out that he was going to check out the opposite bank. I signaled a 'thumbs up', and decided to call my wife. I excitedly told her that we were well underway on our expedition, and that I had just found a good sized limb bone. I also told her that I might have found something BIG, and that I'd get in touch with her later. While Dan continued to wander the opposite gravel bar, I dropped over the ledge to take a few photos of the "dome" in the face of the bank. "Hey Dan, you need to come over here. I want your opinion on something." I grinned inside; there were logistics to work out....my mind was racing! We had over 2 dozen miles to travel...in Dan's nearly maxed out two man kayak. This was going to get interesting.... Proximal "dome" exposed on bank face I spent the next several minutes going over the entire area again. The reason was twofold: I needed to work off some adrenalin, and it's easy to miss something when you're that hyped up. Dan finally arrived, and I guided him to the first bone. He reacted, "Whoa! That's significant! It looks like sloth to me." "I found something else," I replied. We scrambled over the bank and dropped into the mud below the small ledge. "What do you think this is?" I grinned. His eyes went wide and he started rubbing some of the dirt off the dome to get a better look at the details. We both shook our heads in awe. I scooped up some water and splashed it over the dome. Dan rubbed it like there was a genie inside. We both took a closer look, then shook our heads in amazement...BONE! I was a little closer to one of my dreams of finding another fossil giant. We started digging...and the apparent became more obvious as the end of a massive bone slowly emerged from the soil. Suddenly, I turned to Dan, "Did you hear that?" "No; what?" "I hear a boat coming." Now, we are a bit protective of productive fossil sites, but the fishermen (that we eventually engaged in conversation) appeared to be friendly enough. It seems that a dentist, a chiropractor, and their friend wanted to do some fishing. They were also looking for some pieces of petrified wood, so we quickly obliged them with the location of a few large pieces we found upstream. A little later, they returned. We had just extracted the first few pieces of the bone. The largest was close to a saturated 60 lbs. In the time they had been upstream, Dan and I analyzed the transport logistics and boat capacity...we knew we had a dilemma. There was no way we could haul all of this bone more than 20 miles. So, we struck a deal on more fossil wood while I took down some phone numbers and a calculated risk. I placed the large proximal end securely into a corner of the floor of their boat. They thanked us for the wood, and we agreed to meet at a location downstream later in the day. Even with the phone numbers and brief rapport, I winced as they slowly rounded the bend. With a deep breath, I forced the what ifs from my mind; we still had a large piece of bone in the bank. After two and a half hours of bruising, bloody digging into clay and gravel with improvised rock hammers and knives, Dan and I lifted out the final piece of the monster bone. This joint confirmed which part of the skeleton I had found. The "dome" turned out to be the proximal end of a nearly complete Columbian Mammoth humerus (top of the front leg)! It had angled directly back into the bank. Although fractured into several pieces, it was later re-assembled to be just over 48 inches long and around 120 lbs! It's massive and huge! Author badgering the bone Dan working to free the distal end ...Back in the water, we had to rearrange some things on the kayak to achieve proper trim. Tentatively, and with a little fine tuning, we continued our journey downstream. Several hours later, we passed our waterborne associates, and told them we would see them later. Along the way further downstream, we stopped periodically to check likely looking spots for more fossil bone. Occasionally, we would find a large chunk of petrified wood, and stand it up near the water. We hoped to show more goodwill toward our upstream transport team. Author with the distal end Reaching another prime location, we pulled in and started searching. There were many large pieces of fossil wood here, so we stacked them up. With a flash of insight, I reminded Dan that we weren't far from a nearby road. If I could persuade the fishermen to take me and the rest of the bone a short distance further downstream, then they would be free of any later rendezvous. We could pay them with all the petrified wood, and I would also be free of worry. Then, I could hike the pieces of bone to a hidden spot near the road, and go back to the water where he could pick me up. Dan agreed, and within a short time our plan went into action. I profusely thanked the guys for their assistance and we parted company. Near the road, I scouted the area for a hiding place and promptly secured the fossil treasure. A quick survey from all angles left me confident it would be there later. Soon, Dan came into view upstream, and we were off to see what other bounty awaited us. Several other finds were made that rounded out a spectacular adventure. As we loaded the boat onto my vehicle, darkness soon caught us. By the time we reached my hidden cache and got it loaded, it was 10:30 PM. It had been quite a day! Primary pieces Over 48 inches long Columbian Mammoth humerus Awesome discovery!
