Hello, fellow fossil enthusiasts and professionals I am looking to ID an echinoid. I have made some old notes but forgotten how I came to these thoughts, any help will be appreciated. 'CIDARIS INTERMEDIA ?, NOVIEN PORCIEN, ARDENNES.' or location 'THINULE LE MOUTIER' Bathonian stage, Jurassic period, the diameter of the test is approx 25mm, spine about 50mm.
