Creatures of The Mesozoic Seas
By the time of the Jurassic period (201–145 million years ago), marine ecosystems had evolved into something far more recognisable, with fish and reptiles occupying complex ecological niches.
A striking example is a
fossilised Lepidotus fish (estimate £80–120), an armoured species often compared to modern river pike. Measuring over 80cm in length, this Brazilian specimen offers both scale and clarity, with its distinctive ganoid scales still clearly visible. Large fish fossils of this size are particularly appealing for display, bridging the gap between scientific specimen and decorative object.
From slightly earlier in the Triassic period (around 252–201 million years ago) comes a
Keichosaurus hui (estimate £150–250), a small marine reptile from what is now China’s Henan Province. These creatures lived in shallow lagoons and are frequently found in lifelike, articulated poses. China has long been a key source of such fossils, though tightening export controls and increased domestic demand have made well-preserved examples more sought after on the international market.
