Since I started reworking on what was Aquasauria Park, I have been trying to focus the game’s core loop back on the animals. In today’s devlog, I’ll introduce the loop that I’ve been crafting...

I also reworked the user interface, I made it a little more... bio-engineery? The character portraits are still from the old jam version, though.

Two months ago I took part to the #DINOJAM. The theme was ‘Underwater’, so I developed a marine reptile tycoon game. The result was… underwhelming 😅

A little late for the #EuropeanHeritageDays but still: Plesiosaurs are among the most iconic mesozoic marine reptiles of Europe. The first plesiosaur was discovered in 1821 by Mary Anning - a talented fossil huntress and major contributor to paleontology.

As we're all taught, you can (usually) only directly date the age of a rock if it cooled from lava.
But here, scientists have dated dinosaur eggs, using uranium-lead ratios in the calcite. Hugely exciting, maybe groundbreaking.

Scientists directly date dino eggshells for the first time
The new findings narrow age estimates for the clutch of eggs—and may help identify which species laid them
