Here's today's entry, a plesiosaur from New Zealand: Kaiwhekea.
Pronunciation: Kie-whek-e-ah Meaning of name: "Squid eater". Species: K. katiki. Size: Measured between 6 and 7 metres long. Weighed between 1 and 2 metric tonnes. Family: Leptocleididae.

Likely fed on both high and low-growing vegetation. First fossils found: Known from skin impressions and the partial skeletons of several individuals. First discovered in the El Gallo Formation of Baja California, northwestern Mexico, between 1968 and 1974. Named by Albert Prieto-Marquez, Luis Chiappe and Shantanu Joshi in 2012. Was originally thought to be a species of Lambeosaurus. Lived: 74 to 73 million years ago during the Campanian stage of the Late Cretaceous in what in now northwestern Mexico.
Today's entry is a marine reptile from Germany: Westphaliasaurus

Named by Leonie Schwermann and Martin Sander in 2011. Lived: 190.8 to 182.7 million years ago during the Pliensbachian stage of the Early Jurassic in the warm oceans that once covered what is now northwestern Germany.

Named by Ms. Forster in 1998. Lived: 70 million years ago during the Maastrichtian stage of the Late Cretaceous in what is now northwestern Madagascar.
I think they all have vivid imaginations because I very much doubt they can know the skin colour from fossils, but at least the pictures look pretty. 😉
How “lifelike” are we talking? According to Science Alert, the preservation was so good that researchers were able to find out the dinosaur’s skin color.
By using mass spectrometry techniques, researchers detected pigments on the scales of the dinosaur. Apparently, the nodosaur’s coloring was a dark reddish brown on the top of the body — and lighter on the underside.
