Lobster, real or fake?
PrehistoricWonders posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hey, I was wondering if these were real or fake, they look off to me but I’m not by any means an expert, so I’d love some help! TIA -
Here's part of a upper lias fossil lobster, i found this at Whitby on the coast before the Covid lockdown earlier this year. I believe the species is Glyphea I do enjoy looking for fossil lobster nodules on the yorkshire coast in England so i'm trying to figure out exactly what i have here. I was told this is a left cephalothorax. So do i have a head and 2 front feet? Or is it the head from a side view. If any body can find any useful diagrams/pictures of what i have it'd be much appreciated. Thanks Liam

Hi, Attached are photos of a small 5.5cm lobster I finished prepping. The original semi-prepped lump I purchased was identified as Shrimp or Crayfish, Cretaceous Period, from England. My research identifies it as a Meyeria Lobster from the "lobster beds" of the Greensand Formation, Fissicostatus Zone, Atherfield on the Isle of Wight, England. Does anyone have additional or corrected information?

Found yesterday on limestone quarry near Cracow. Site is confirmed 100% jurrasic. Before any preparations I want to be sure what I'm dealing with. Could it be a part of a lobster?

Memorial Day hunt. Site 2 Denton Creek. Paw Paw Formation? of Washita Group
KimTexan posted a topic in Fossil Hunting Trips
This is part 2, site 2 of my Memorial day fossil hunting trip. You can see the site one report here: I chose to drive out to Denton Creek north of Ft. Worth. I had been there before, but had not gotten to explore the area. It was the takeout point from a kayaking trip I’d taken down the creek a few weeks before. It took me 30 minutes out to drive out there from the first location I hunted in Benbrook. If you pass the creek going north you can go up to the next exit and then loop back to the creek. There is a little rock and dirt path off the shoulder of the road that leads down to under the bridge where you can drive your vehicle. The hill down to under the bridge is kind of steep. My car was a bit on the low side for getting over the curb and then a steep embankment with rocks. I bottomed out once. I thought I might park my car in the shade under the bridge, but when I arrived there was another vehicle in the area. I thought I was the only person crazy enough to be out here in the heat. Nobody could pass if I parked under the bridge so I pulled through into a small clearing there. The grass and weeds were grown up pretty high in the clearing. I knew of a sizeable exposure on the creek that I wanted to try to get to on foot, but I didn’t know the terrain around the creek. I switched to my rubber boots for walking in the creek. I reapplied sunscreen and headed down the steep hill to the edge of the creek. I had to sit down and scoot myself over the edge and drop down to the rock ledge that ran along the creek. I inspected the exposure. Last time I was here I found a pretty decent Macraster obesus right by the spot I came in by. I didn’t see a single fossil. The creek was maybe 40 feet wide give or take. The water was less than 10 inches deep where I entered the creek. I don’t think the creek is ever a high energy creek. The rocks that are in this part of the creek are angular and jagged. The water in the creek is rather murky so you can’t see into the water. All of that makes it a difficult creek to walk in. Most of the creek in that spot is one level at bedrock with rocks scattered across much of the creek bottom. There is a narrow jagged rift in the bedrock that meanders along the creek bed. The water is deeper in the rift. I walked down into the creek and squatted down looking at some ammonite fragments in the creek. I saw two butterflies nearby. I tried to get a better picture from the side, but they flew away before I could do so. Sorry it is not a very clear picture. You can see the creek bed is kind of slimy looking. In some areas where the water was very low it looked foul and fetid. It had a green bubbly looking surface. I assessed the creek and decided to walked along the exposed rock ledge above the creek. As I walked up the creek there was a horrible stench of something dead. The further I went the worse it got. Finally I came upon a gar fish carcass on the rock ledge above the creek. It was close to one of the places where I had wanted to have a look around, but the odor was too strong and repulsive. It looked to be just over 3 feet long. I can’t imagine how it got there. It had to be a person who had drug it there. This section of the creek does not seem deep enough for such a large fish to swim in. Maybe it swam in the rift though. There were deeper sections of the creek where it could live, but not here. There were signs of racoons all over along with remnants of their meals. Evidently gar is not on the racoon menu, which was surprising to me since it seems raccoons will eat almost anything else. I looked at the thin, razor sharp gar teeth. It is kind of scary to think that type of critter was in this creek when I kayaked it. I was in and out of the water all the time. A bite from that thing would be nasty. Here is a pic of it. I walked back down the creek upon the rock ledge to a place where there weren’t too many jagged rocks in the creek and where the rift in the creek would be narrow enough for me to step across it. Since the water was flowing slowly the rocks were covered with algae and were very slippery. I got to the rift. There were rocks pilled up there. I place one foot on a large one sitting at an angle and it tottered underneath me. I made sure my foot wouldn’t slip and I balanced myself as I put my next foot on another rock. It tottered too. To slip and fall in this creek with all the jagged rocks would really hurt and might do considerable injury. At least when I slipped and fell in the NSR the riverbed was smooth, without any rocks. I took a few more steps on similar rocks and I was I on smooth riverbed again near the other bank. I began to inspect the exposure. I found these just sitting on the bank. A cute little impression of an ammonite and what appeared to be a fragment of a Pinna clam. I have yet to find a whole Pinna clam. I’d kind of like to find at least one whole one someday. The only other formation I have found them is in the Goodland. It is another of the Washita Group formations.- 12 replies

Hello to all fellow fossil lovers. Ok I found this at the Lincoln formation in porter wa. At first I tried to relieve it from its cast by striking it with a hammer. Then I soaked it In Vinager and chipped away at it. I decided that I would ruin it if I continued. I froze it and thawed about 4 times. The end fell off as you can see. Is this a lobster or shrimp? How do I finish exposing it?

A little Psuedoglyphea sp. from the Whitby mudstone formation, found at Sandsend near Whitby. A rather rare find due to the carapace and mandibles all being there. Usually you find the odd mandible or legs. It sits proudly in my collection already, and it’s not even been prepped yet. Next month it’s being sent off to be professionally prepped

I cant tell you how long this has been sittin in a box collecting dust? I tossed it aside many years ago when I realized after many hours of prep that it was only half a lobster!!! Today my youngest son and I were going through some old boxes of stuff and ran into this today. He was saying how cool it was, and I have to say I agreed with him,,,,, so to the saw it went! Never in my life have I ever cut a lobster concretion in half! I was also nervous about it and wondered if by chance we would somehow run into the other half,,,,,, but no, there really was no other parts of the lobster in the half we cut off. This lobster in some bazar way is half a lobster lengthwize!!! Imagine cutting one from the tail end up the tail the body, the head and leaving only one claw! How in tarnation does that happen???!!! Anyways, here is a picture of it. Hart to see but look closely. Tail end on the left and big claw on the right. This is now back on the preppin block. Just need time. RB

Just sharing afew of my finds i've been working on today. Firstly a big, marine reptile or fish coprolite that i expected to pop out of the matrix. I'm not sure if it'll look better kept in, but it's pretty delicate. Secondly a lobster, claw or body part. Not sure which. Remember i'm still new to prepping, so everything is new to me.

This was labeled to be a Carpopenaeus sp. shrimp from Lebanon. I had a sneaking suspicion that it may not actually be a shrimp, but perhaps a lobster because of what appears to be claws so I purchased it. I was looking for second opinions on this fossil and will try to update with a closer look when it comes in (shipping is overseas and will take a while though).

Given to me by a member of the Australian Fossil Club. Will add more information about the formation soon.

About two or three years ago I bought this lobster concretion from a guy at the Gem and Mineral show right here in Helena Montana. Ive been working on it here and there and its finally looking like a lobster. Ive still got about 20 hours to finish this one up? This one is known as Hoploparia. The longer clawed ones are known as paleonepherops. I have the longer clawed ones, but now I will have the shorter clawed one too. Life is good! Oh, and also a picture of the longer clawed one to show the difference. RB

I was hoping someone could recommend a fossil prepping service in the uk. Ideally south east England. I have found what looks to be a virtually complete meyeria lobster from whale chine, Isle of Wight, uk. About 15cm. Fairly big from what I understand. It looks like it could turn out really well, but it’s such a complex prep, I was thinking it’s better someone with experience did it. If anyone could recommend someone who may be able to help I would be most grateful. Many thanks henry

Last January I was givin a box of fossil lobster concretions. I told the guy to give me year and I would bring him back a prepped out lobster as long as i could keep the rest. Most of them made it to the trash can. Very hard to get a decent fossil lobster!!! This one is not the best, but far from the worst. This one was actually good enough to prep. here it is. I think he's gunna like it? RB

Saltwick Bay Field Trip, sitting down on the shingle to have a bite to eat, looking down at the pebbles around me as I always do, just in case, you never know. Noticed a pebble with a slight nick in it and thought 'I wonder if I bash it will there be anything inside' Well I did and this is what I found. If I remember correctly I was told it was Jurassic and a Pseudoglyphea lobster leg. One day I may try to prep it but matrix really hard. 1 - pebble 2 - One side of inside 3 - The other side of inside 4 - Close up of part of leg showing spines on leg, some of the blue surface still there. 5 - Close up including what I think is a joint. PS. I thought I had posted this the other day but it popped up when I tried to list another post, no pictures so hopefully this is going to appear and I have not done it twice.
