- Seems unlikely.
-
- 1) lizards aren't closely related to dinosaurs. No forked bird or croc
- tongues.
-
- 2) most lizards don't have forked tongues. Varanids and the related
- Helodermatids (Gila Monster, et al.) are the only ones that I can think of.
- The presence of a forked tongue in varanids & some fossils are pretty strong
- evidence that snakes evolved from this group.
-
- 3) forked tongues are usually associated with Jacobson's organ - a
- chemosensory pit on the roof of the mouth. I've never heard of dinosaur
- skulls with such a pit, though I'm not sure it's presence or absence can be
- determined by bony remains.
