When my youngest son and I went on a fossil crab trip just a couple of weeks ago, we parted ways and I went up to the Seattle area and he went to Oregon. He found this awesome Raninid claw along with whats left of the ventral part of the crab. He is going to keep this awesome beautiful beast! Cant blame him.

Found on construction site. The deposits correspond to a shallow and very saline lagoon environment where few species coexisted.

Looking to trade limestone for shale.
joshuajbelanger posted a topic in Member-to-Member Fossil Trades
Hey, looking to trade Ocala limestone, very fossiliferous with calcite inverts for any type of fossiliferous shale. We can discuss amounts later. Will also send you pics and let you choose your specimens. Or I will trade bone valley fossils for the shale. Have peace river and mined fossils, so colors and types vary. Thanks! -J -
Its been almost a year sence I went on a fossil hunting trip. A bit early too. My youngest son decided he wanted to go visit an old school buddy who lives in Oregon and wanted to know where all my fossil crab locals were, so I decided to go along for part of the trip and just show him. Sad that lots of crab sites are closed now, and not only that, but found another site just recently closed too! Brand new gates everywhere! Anyways, it took us 2 full days of driving and hunting to get the first 4 sites done, then we said our good bys and he went onto Oregon and I went back up into Washington to do some trading with some crab guys. I took along about $1600 worth of trading material so I was quite prepaired for some wheeling and dealing. Got rid of all of it and turned it into more crab concretions. Now ive got about 2 or 3 years worth of crab balls to play with. Here is a picture of my son way up on a cliff side that I would not intertain myself nowadays. RB

This is my first post here. I'm a writer and photographer. Because of circumstances I have been forced this winter to photograph mostly at home, so I started doing some macro photography. Then I found interesting leftovers from the spiders in the basement, and long story short; I started taking pictures of insect inclusions in Baltic Amber. The difficulty of the subject matter intrigued me greatly. I have started to read "History of Insects" by A. Rasnitsyn, D. Quicke (Kluwer, 2002), to understand amber and inclusion process, and "Insects of Britain and Western Europe" by M. Chinery (A and C Black, 2007). I'm trying to be able to identify species and families. I have learned that one of my fossils is a Diptera Nematocera, which means two-winged midge, and thats good enough for my project. Because I plan to get a wider collection, and maybe an exhibition of some sort. So I'm asking for some help with this, and if it's ok to post regularly when in doubt. If someone here could not only tell species and family, but also what the identifying markers are. I'm a fast learner, and will not bother you if I have nothing to show, or can figure it out myself. I try to study, but need som assistance to get started. Fossile insects are not as easy as spotting a bee or wasp or fly. So here are my first images. I have tried to name one or two, but like I said, I no next to nothing of my subject matter. (I have education in anatomy, and a rudimentary understanding of insect parts, but need pointers to put the puzzle together). The size of the inclusions are 2-4mm in body length. All are probably from the Eocene period. Thanks! I am puzzeled by the head of this one. I just call it a Diptera for now. Someone on a forum told me this was a Chironomidae, but why? The bug on the bottom looks like a Weevil. I think this is a Midge hunting an ant. If it is a Nematocera. But it looks like it has hair on the body. Is this a wasp or a fly? I have no idea. A fellow photographer called her a "Ikea bug" Some assembly required:) The seller of this one called her a Diptera Nematocera, or a mosquito of some sort.

Here is a crab I got from John Spina. This poor crab has almost no leg to speak of but has some very nice 'leoperd spots' on the arms. Im going to build a bunch of legs on this one. I also used a special 1 inch cube made by Ray-Aero Grower for scale. Thanks so much Ray. I feel I need to somehow reciprocate. That was just super duper nice of you. This is going to take some time cause im now back to working on the house and im gunna be gone for a week or so going to Washinton to go get me some more crab concretions. Could be 3 or 4 weeks, maybe more? RB

This echinoid is about the average size for this sub species. Eurhodia rugosa subspecies ideali was erected by Porter Kier in " The Echinoids of the Middle Eocene Warley Hill Formation, Santee Limestone and Castle Hayne Limestone of North and South Carolina" 1980

Recent Sphyraenea barracuda, own work of Laban712 (from Wikipedia): The genus Sphyraena (from Latin: "pike-like") belongs to the order Perciformes. Members of the genus Sphyraena, better known as Barracudas, are elongated fish, pike-like in appearance, with large pointed heads and jaws. The two dorsal fins are widely separated with the anterior fin having five spines, the posterior fin having only one spine and nine soft rays. The posterior dorsal fin is similar in size to the anal fin and is situated above it. Barracudas normally have an under bite with prominent sharp-edged fang-like teeth in sockets. The oldest known barracuda fossil found so far dates to the Eocene period. All members of the genus Sphyraena are voracious predators; they feed upon cephalopods and crustaceans but mainly prey on fishes. Young barracudas can be often seen in small schools. Adult barracudas are considered to be solitary when it comes to hunting. The great barracuda can swim up to 35 mph, yet it can move forward slowly with no apparent effort; thus increasing its stealth. Barracuda are found primarily in tropical and subtropical waters of the Atlantic, Indian, and Pacific oceans, but certain species such as the Great Barracuda lives in brackish water.

River water has been too high lately for me to access my favorite sites so I had to settle for a very small Eocene Castle Hayne outcrop that I can walk to. I wanted to see if the floods from Hurricane Matthew had much effect on the outcrop. On the walk in I found a pretty nice projectile point sitting in the sand. It is a variation of a Guilford stemmed point made out of rhyodacite. This material is almost black when fresh and weathers to green and then almost white. I found a new exposure of Castle Hayne Limestone and the root of a nice sized Otodus auriculatus was poking out. Old exposures got covered up from the floods. The Otodus auriculatus was unusual in that the serrations were very large. The last photo shows a similar sized Castle Hayne auriculatus with much smaller serrations.

My family and I usually visit the Frio River in Leakey, Tx every summer. A few years ago we were all set to go swimming but upon arriving we saw that the part of the river we usually frequent had dried up. I decided to make the best of it and explored the dried river bed looking for anything interesting when this isolated chunk of rock caught my eye. I picked it up off the ground, took it home with me, put it in a drawer and forgot about it. A few months ago I found it while doing some cleaning and realized it had to be something more than just an oddly shaped rock. I cleaned it with water and a toothbrush after reading online that that's a simple way to clean fossils. A friend of mine with limited knowledge of fossils suspected it was some kind of fossilized coral or sponge. What I originally thought was matrix does look a lot like syringopora, but I can't find pictures of any prehistoric coral fossils that match the appearance of that hot dog in the center! I saw a sperm whale tooth on this forum that looks similar but I'm not sure if what I found feels like a tooth. It feels way too smooth to me. I love fossils and I own some shark teeth, coprolite, and a little trilobite, but those were all bought. If whatever this is turns out to be something, then it would be the first fossil I've ever acutally found myself. I'm still really new to this so please forgive me if I am asking silly questions or submitting this incorrectly. Any insight would be greatly appreciated!

Taxonomy from Fossilworks.org. The order Beryciformes, a poorly understood group, is represented in Monte Bolca with at least two species: Eoholocentrum and Berybolcensis, both from the subfamily Holocentrinae or squirrelfish (L. Sorbini, 1984). Both species seemed to be largely or entirely nocturnal and lived in deep marine waters; their eyes are amazingly large. References: Sorbini, L., 1979. Les Holocentridae du Monte Bolca. III. Berybolcensis leptacanthus (Agassiz). Studi e Richerche sui Giacimenti Terziari di Bolca 4, 19–35.

Hi Folks, I am taking the opportunity of terrible weather here to sort out some of my fossil finds from last year. This set of specimens comes from the Middle Eocene Allenby formation on Allenby Road near Princeton British Columbia Canada. The main structures I see are the shiny patches of material that resemble the slickinside we see in our concretions here on Vancouver Island. The material does not appear to have much depth. The rock is a cherty mudstone. Patches of sheet like algae? Mud striations?

Diodon holocanthus, inflated (own work of Ibrahim lujaz from Rep. Of Maldives) Diodon nicthemerus (own work of user Springcold at da.wikipedia) Porcupinefish belong to the family Diodontidae within the Tetraodontiformes order and are also commonly called blowfish. They have the ability to swallow water or air and to inflate their body making it harder for predators to swallow them. When the fish inflates, sharp spines radiate outwards as a second defense mechanism. Some species are poisonous, having tetrodotoxin in their internal organs. Fugu is the Japanese word for pufferfish and is also a Japanese dish made out of the pufferfish meat. Because fugu is lethally poisonous if prepared incorrectly, fugu has become one of the most celebrated and notorious dishes in Japanese cuisine. Porcupinefish are medium to large sized fish and are found in shallow temperate and tropical seas worldwide. Monte Bolca is an important lagerstatte for Tetraodontiformes with Diodon tenuispinus as one of its oldest records. References: J. C. Tyler and F. Santini (2002) Review and reconstructions of the tetraodontiform fishes from the Eocene of Monte Bolca, Italy, with comments on related Tertiary taxa.

My youngest son goes fossil hunting without me these days and a few years ago he went to the parachute member of the Green River Formation and found some fossil leafs. He asked me the other day if I would do a prep job on a leaf he had found. I said "sure". So, he brought it over and I did some 'prep majic on it. It didn't look too good when I first took a gander at it, but I figured I could get some tips out of it and expose the stem. The more work I did on it the better it got. The bad thing was the leaf itself was not in very good preservation with the rock very discolored around the leaf making it hard to see. So, the mind got to thinkin and then I decided to do a bit of artwork around it. I have to say that was a good idea. Still have a ways to go but its coming along quite nice!!! One of those fossils where the more you do the better it gets. RB

Hi all! Here are three sharkteeth I have from Balegem, Belgium. The sharkteeth there are from the Eocene. Those will soon go into a trade, so I need to get an ID quickly! Right now, the ID I have is this (from left to right): Physogaleus latus, Lamna nasus, Jaekelotodus trigonalis. Are those ID correct? Best regards, Max

Most of my fossil collecting has been Invertebrate Macrofossil collecting. Very little attention has been made to the little fossils. It is always a good idea to expand your knowledge, leave your comfort zone, go somewhere you have never been before. I find that not paying much attention to Microfossils has been a mistake. So when I saw an interesting Nummulites fossil slab for sale; I chose to purchase it. The rough cut specimen looked like it could reveal more, with a little attention. What I chose to do is give it a good high luster lap polish to see the results. So much more detail was made. Where my specimen came from was Northern Spain, in or near the Pyrenees Mtns. near Aragon. The seller didn't give much info and what he did give was in Spanish. Chasing information down on the internet I found the mixed fossils were Nummulites sp. (large ones) and Alveolina sp. (smaller ones) I have some photos of my results to share. Before polishing it looked like this: After polishing the fossils clarified, here are some closeups: Apparently these fossils are common in Spain, neighboring France and other places in the world. This is an old engraving: In Spain, the Limestone the Nummulites are in, is used as building materials like blocks, steps, pavers. I will need to do more studying of these neat looking spiral tests.

Pesciarichthys baldwinae Sorbini & Tyler, 1998 was redescribed in 2012 by Bannikov & Tyler and the new genus Frigosorbinia established. Taxonomy from Fossilworks.org. Diagnosis from Bannikov and Tyler 1998, p. 27:" Body a deep ovoid in shape; head relatively small. Mouth small; teeth relatively small and lobate. Five branchiostegal rays. Vertebrae 22 (9 + 13); haemal spines of first two caudal vertebrae slender, oriented posteroventrally, and not in close proximity in their middle regions. Tenth caudal vertebra with elongate slender neural and haemal spines. One supraneural. Dorsal fin with eight spines and 23 soft rays. Both first dorsal-fin spine and first anal-fin spine protrude to exterior. Anal fin with three spines and 21 soft rays. Tenth interneural space with two basal pterygiophores; 11th space with one basal pterygiophore. First interhaemal space with two basal pterygiophores. Pelvic bone with relatively shallow subpelvic keel (12% of pelvic length). Scales very small over most of body and head. Each scale consists of a small basal plate with upright spinules. Larger rounded scale plates scattered posteriorly on body in region of caudal peduncle; these larger scales are densely spaced together and slightly more than twice the size of the small body scales elsewhere. Caudal peduncle with three moderate, fixed, keeled bony scutes." Line drawing from Sorbini & Tyler 1998, p. 25 : Identified by oilshale using Sorbini & Tyler 1998.

Here it is my pleasure to quote Auspex: "Messelornis is often incorrectly referred to as the "Messel Rail". Although rails are in the same order (Gruiformes, along with the cranes), its closest living relative is the Sunbittern of the American tropics. There are four named species (of two genera) in the family Messelornithidae: Messelornis cristata (only from Messel), M. nearctica (from the Eocene Green River Fm., USA), M. russelli (from the Paleocene of France), and Itardiornis hessae (from the Late Eocene-Early Oligocene fissure-fillings in Quercy, France). According to Gerald Meyer in Paleocene Fossil Birds, there are over 500 specimens of M. cristata known from the Messel pit, constituting roughly half of the bird fossils found there. Interestingly, no juvenile specimens are known from there, which suggests that they did not nest nearby."

Here it is, the show booth layout! What do yah think? did we get enough fish this year? I am kind of fond of the table, it is fully lit all the way around the inside with LED lights!

Hello TFF! I just wanted to take a minute to share with everyone some of our finds from 2016. I do most of my digging up in Kemmerer, WY trying my hand at fossil fishes. 2016 was a pretty exceptional year in that along with our standard hundreds of 18" fish and thousands of split fish we pulled 2 VERY LARGE specimens. quite rare really. it averages out to about 1 every 2 or 3 years normally, so 2 in one summer is AMAZING! These panels have all been finished and are ready to hit the market along with the large gar and the croc! Fingers crossed that they sell so we can open up next year! I hope you all enjoy coming along. ALL of these panels feature 100% natural fish with 0% restoration. NO PAINT, a few have been inlaid though. In the last picture, the branch does have around 2% restoration because it was in multiple pieces needing to be glued.

The misses and I went to quartzite for a small vacation and just got back yesterday. We also went last year and had so much fun that we decided to go again. I have friends that have been going there every year for the last 18 years and it was great to meet up again. I use to sell there for about 8 or 9 years but quit once I realized it was turning into a job. I use to do 7 or 8 shows a year and went down to 0 for the last 10 years. I did take some fossils with me. I had a spot about 4 feet wide. Just to keep me a busy, kinda. I did help my buddy do quite a bit of selling, but for me, I was just there to sip wiskey, shoot the poop and have fun. I didn't even have to try and sell the crabs I took with me. Once people pick them up and hold them in their hands and see them close up, they sell themselves! The crabs I sold payed for the trip and the stuff I bought and the next two trips also. Just a neat hobbie. I took 17 prepped out crabs with me and sold 13 of them. Looks like the price for crabs are going to go up next year yet again!!! I really cant believe how much I get for these. But all in all it was a great trip, made lots and lots of moneys and had a super good time with lots of drinks, lots of good food and lots of good times.
