Ocean life encyclopedia
Blue Life Commons now has an image-first species encyclopedia: approved media hosted in Vercel Blob, source pages preserved, and every animal connected back to its cited public record — plus a new Deep Time guild for Mesozoic marine reptiles (often misnamed “ocean dinosaurs”).
44

Species grouped for scanning and expansion.
Special section · Deep Time
Mosasaurs, plesiosaurs, pliosaurs, and ichthyosaurs ruled Mesozoic seas. They are not dinosaurs. This educational guild pairs sourced paleontology notes with clearly labeled AI concept reconstructions — never fossil evidence.
13 deep-time entries
Living ocean wildlife remains the core of Blue Life Commons. Deep Time is the bridge that makes “sea monster” curiosity accurate.
44 approved images · 31 Blob-hosted images
Candidate media remains out of public rendering until approval. Deep-time heroes use labeled concept reconstructions.
