The lobster is Thalassina sp. from Indonesia?

After finding another example on this site the crab is Zanthopsis sp.

Both are in decent condition I think. I can't see the claws of the lobster good enough to see how much restauration there is.

The claws of the crab seems to be reglued.

 and thanks, considerng that the lobster seems to be a lot more than the crab and you seem to have the site that i am looking at what would your imression be + more pictures of claws

Well, the claws seem to be both glued. The restauration will be probably be in the form of matrix and glue mixed together to fill gaps. I see a couple of spots that might have had this restauration.

 

The red lines show the possible glued fractures on the claw.

 

The third picture is from a different specimen I found online (probably the same seller since the background is the same) with two more obvious restaured parts to show.

In answer to your question, I personally would prefer the crab on the rock.

Me too.

Those Thalassina range from Pleistocene to Holocene and are often very difficult to distinguish recent from old ones, they are also often composite Regarding the Zanthopsis, the speciment is not on his original matrix but is placed on a more attractive rock (from another non fossiliferous location). Plus arms and pinchers appear to be opened, as often happens to make them look more aggressive.

They are both ok, but it think you would like to know about that before bidding

The restoration that I see appears to have been required in order to put all of the pieces together. More like a repair in my opinion. I would go for the lobster personally, but that may just be because I have never personally collected one in good condition.

@will stevenson The choice is up to you now as long as you can afford the one or the other

[Bobby Rico]

I like

the crab myself  more than the mud lobster but both quite nice. Only you can choose.

Either look nice to me but I would choose the lobster. At least if I didn't like it, I could convert it into a shoe horn!! If purchased, I would definitely mount it to a piece of driftwood or something to take away from a little of its starkness.

 Youve got some good advise here.  The only things i would add is that there used to be a guy who was selling these lobsters that would take your money and not send the lobster.  I was going to buy one till my buddy lost his money on two of these.  I rarely buy fossils and trust almost no one.  Sad to say.   Your Zanthopsis looks to be dufori.
