However further interrogation of the fossil: the shape, the fact that the growth lines are on one side of the shell but there is no sign of adductor muscle scars, palial sinuses or other characteristic bivalve signs, and the 'bobbled' texture on the plate, leads us to the conclusion that this is not from a bivalve.<br /><br />Rare examples of ammonite shells with aptychi preserved articulated have shown these plates to be located in the body chamber of ammonites. Upon death most pairs of aptychi disarticulate and hence they are found as single plates, such as this one.</div> </div> fingernail Jurassic smooth https://wserv3.esc.cam.ac.uk/p1acollections/files/original/0bff3979aaa02b655e03f0244e6e8652.png a2542186f8fd5df501c68b5c857a684e https://wserv3.esc.cam.ac.uk/p1acollections/files/original/522ed4d8bd22839e1d69d88433a5237a.png f1065aa2b9e620e4759d55e98df3fb3e Physical Object An inanimate, three-dimensional object or substance.
