The argument concludes that lizards did not evolve from anthracosaurs. How do we know? Because we haven’t found anthracosaur fossils in rocks older than 300 million years, but we recently found a 340-million-year-old lizard fossil. And of course, lizards could have only evolved from creatures that predated lizards.

The argument assumes that there are no anthracosaur fossils that are older than 340 million years. If such a fossil existed, the support for the conclusion would be destroyed, because we could no longer claim that lizards predate anthracosaurs.

The argument tries to establish that lizards predate anthracosaurs to conclude that lizards can’t have evolved from anthracosaurs. However if these fossils did exist, then we couldn’t establish that lizards predate anthracosaurs, so the conclusion would be unsupported.

The argument relies on the idea that lizards predate anthracosaurs because of each group’s oldest known fossils. Having even older lizard fossils wouldn’t change this, so like (E), this isn’t necessary.

The argument explicitly states that we now know of a lizard fossil which predates even the oldest anthracosaur fossils, so this assumption would just be contradictory.

The argument relies on the ages of the oldest known fossils for each group, so just saying that some anthracosaur fossils predate some lizard fossils is irrelevant.

Like (B), this is irrelevant because the argument has already established that the oldest known lizard fossil predates the oldest known anthracosaur fossil, and this doesn’t add anything useful.
