Socko Strong was an Earth-Two character, and he spent some time on a dinosaur-inhabited island. Okay that particular island volcanically blew up, but still, in its brief time, it was an Earth-Two version of "dinosaur island". Stoop Davy Dave (talk) 00:24, March 27, 2018 (UTC)
- This article is about one particular island. "Lost worlds" full of prehistoric life go back at least to Arthur Conan Doyle, but we probably don't need to list all of DC, Quality, Fawcett and Charlton's versions of that trope on this page. DrJohnnyDiablo (talk) 03:05, March 27, 2018 (UTC)
