       Dipnorhynchus is a genus of primitive lungfish that already shows changes from its sarcopterygian ancestry.‭ ‬The skull is no longer in two halves and instead,‭ ‬in the loosest terms,‭ ‬forms a box.‭ ‬The palate of Dipnorhynchus was fused to the skull,‭ ‬like in land dwelling animals,‭ ‬and instead of having cheek teeth,‭ ‬Dipnorhynchus had dome like protrusions on the palate.‭ ‬The form of the‭ ‬palate and the fact that it’s was fixed to a solid skull indicates that Dipnorhynchus most likely hunted for creatures such as hard shelled molluscs and invertebrates,‭ ‬the shells of which could be easily broken up by the crushing palate.
