Oh okay then Tigrex starts the Flying Wyvern family path after Saurischia Akantor and Ukanlos started there own path from Saurischia.

Saurischia includes splits such as: Akantor and Ukanlos Flying Wyverns,Flying Wyverns,Bird Wyverns and Theropods(Brute Wyverns).

At the start of the FLying Wyvern path is Tigrex and his relatives after that splits include Shell Wyverns(Rath family starts here),Armor Wyverns(Blos and Gravios familys),Strange Wyverns(Yes Khezu and Giginox splite here),Uknown splits that leads to Snake Wyverns(Remobra and I guess he has more than 1 species out there) and last another unknown split leading to Barioth and Narga familys meening they are close related.
