We are to take "virtually identical" to mean "similar," since as you can see for yourself the forms are similar but most definitely not identical

That is due to the fact that they are drawings and have this proviso.

Details of the fossil's supplementary tail fin are insufficiently known to allow restoration.

So what? There are plenty of differences around the eye (as I noted) and in the rostrum, the lower jaw, etc. And there is the difference in size, and in habitat (all fossil coelacanths are shallow water species, and many are fresh water; the living genus is a deep ocean species) and adaption thereto.
