Is This Fossil Fake Or Real?

Recommended Posts

Hi,

I bought this fossil but I have doubts if it's real. How can I prove it's fake or not?

Here are some photos:

All I can say is that the shrimp has been enhanced with inc or pencil.

Where did the fossil come from and how much did you pay for it? If it comes from china, it's likely to be at least partially fake, especially given how perfect that shrimp looks.

The fish seems real enough, but the shrimp is extremely suspicious.

As others have said fish looks real, shrimp mas definately had major portions drawn in, may well be a fake shrimp

I think color has been added to the body of both the shrimp and the fish... Cool fossil as long as the work was communicated prior to purchase.

i would say both are real but I don't like how they have over high lighted the shrimp with pencil or dye? I have fish from the green river formation and they all have dye or some sort of dye to high light them, in some cases painted fins on that were most likely there but no fossil proof on the rock. same with the shrimps I think when found some are faint and hard to see so they paint them in with dye. some people like it others don't. For what you paid it should be real. Tpost-10263-0-68671200-1358281883_thumb.jpghis one is off ebay look on there to compare.

You are correct adie! I've done my fair share of prep work in my time, and although the shrimp you show itself is real, even that shrimp looks as if it also has painted/ hilighted appendages and antennae

The gloss on the shrimp looks real, at least.

I don't know fish very well, but the shrimp looks like the common Cretaceous shrimp from the limestones of Lebanon. If the fish is one of the known species from those same limestones, it would suggest that the combination is correct and likely real.

I agree.... authentic shrimp fossil with highlighted details added.

Congrats on a great display specimen with a fantastic fossil fish happy0144.gif

I agree with what people say about it coming from Hajoula, Lebanon.

This is one of mine from the Cenomanian of Lebanon. Carpopenaeus callirostris. It has not been touched up (as far as I am aware), if needed as a reference. Two complete shrimps lying nose to tail on matrix.

When I enlarge it and squint, I see that whoever applied the shiny finish didn't stay inside the lines that well. I think the shrimp is, at best, a partial carapace.

The fish does not have vertebrae present. Highly suspicious. If it is real, it isn't the "good side".

think its only missing some verts tail end, think when slabs are split open some verts may have come off in the other section....makes me wander...do they prep both halfs of the slab? normally 1 half with the bones and the other half the impression (maybe a few bones too) preb both = 2 fossil slabs from 1 fish? also, if you get the chance in shop to look at a few fish on slabs look on the back you sometimes see un prepared fish, some do have a natural colour others are like ghosts .

I agree with the others regarding the shrimp. The fish looks to have had some enhancement with color added to the dorsal and caudal fins.the skull and spinal column actually look pretty legit with minimal or no restoration. The preservation is fairly typical for these Lebanese Cretaceous fish.

These fossils actually fluoresce quite nicely so you may want to check it out with a fluorescent bulb in a dark room. I have found the reaction to be more subtle than one will see in green river material, but it is a useful test.

This may come as a surprise, but that shrimp has been touched up. I know, I know, it is a shock, but it's true. :o The fish may have had a bit here and there as well. Nice piece though.

It is pretty common to see these shrimps with an added outline... probably because the original fossil is not complete, but this makes it look complete. I disapprove, but that's just me.

It's not just you. One could draw a shrimp on a bar napkin, and it wouldn't be much different.... well, that may be just me. :)

lol, I purchased a very similar fossil plate when I was in Spain about 10 years ago.

I was a bit of a novice back then and in my teenage wisdom snapped it up.

A decade later and I am the proud owner of a very enhanced Lebanese shrimp and to add insult to injury my girlfriend at the time having no knowledge of fossils said to me "That prawn looks like someone has just drawn it on with a pencil".

Oh well, you live and you learn.

Yeah, I guess the fossil ir real, both the fish and the shrimp but it has been "enhanced" with some color or whatever... Personally I would like it natural, without any dye, but still a nice fossil.

Here you can have a closer look to the shrimp. Also I noticed that the fossil was broken in two pieces and then reattached (if you look at the tail of the fish you can see that the crack is really hard to notice because it has been painted with the some color of the fish).

Thank you all for your help!

Nearly all of the fish I see for sale at shows are inked in, or have some element of ink used in the presentation of the fossil. I think it just comes from people wanting money fast, a lot of the Green River fish I see are inked, it looks, but i can't be certain that they have been blasted with an air abrasive, all the bone and skin has been removed, what you end up with is an impression on the plate rather than any actual fossil material and it is this that is inked in and sold to the public as a 'fossil fish specimen'.

Regarding your specimen, just looking at the images, it is clear to see that the shrimp is penciled in (as stated by many here) The fish does look to be inked, in places. Mainly just on the fins.

These are a few I prepped before Christmas, These are the first Green River fish that I have prepped. No ink was used just air abrasive and a paraloid coating. Although the paraloid does colour the rock giving the fish a better outline, Is this the same as inking?
