       Analysis of Obruchevichthys remains has struck up similarities with a tetrapod named Elginerpeton. This has revealed that Obruchevichthys was also a member of the early tetrapods, not a lobe finned fish as first thought. Along with Elginerpeton, Obruchevichthys predated the other tetrapods by an estimated 5-8 million years.
