Three examples of echinoid fossils from my museum; the determination was done by me.
1. Heliophora sp. – from a Miocene standstone formation in Northern-Africa. This species is now excinct.
2. Scutella sp. – Oligocene to Lower Miocene of the Mediterranean region.
3. Mepygurus depressus – Callovian, Middle Jurassic of Madagascar
