Echinoids and Sand dollars
Part of the larger family of the Echinodermata, These include Brittle stars, Crinoids, Sand Dollars, Sea Urchins, sea cucumbers etc.  STARFISH / BRITTLESTARS are on their own page.  The earliest echinoid fossils date to the upper part of the Ordovician period (circa 450 Mya), and the taxon has survived to the present as a successful and diverse group of organisms. Spines may be present in well-preserved specimens, but usually only the test (shell) remains. Isolated spines are common as fossils. Some echinoids (such as Tylocidaris clavigera, from the Cretaceous period's English Chalk Formation) had very heavy, club-shaped spines that would be difficult for an attacking predator to break through and make the echinoid awkward to handle. Such spines simplify walking on the soft sea floor.

Sand dollars first evolved during the Eocene.
