Comparison of two Smok reconstructions by Szymon Górnicki.
Smok wawelski, named after a polish dragon, is a species of extinct archosaur that lived 205-200 MYA in Europe. We aren't sure what group it belongs too. It could be a rauisuchid, prestosuchid, pseudosuchian, or even a theropod. It ate fish, dicynodonts, and temnospondyls.
