Tetragraptus fructicosus. This biomineralized exoskeleton was also morphologically complex, bearing traits that had ecological significance, and was present throughout postembryonic development, from larval to adult stages. Tropites is characterized by a distinctive, easily recognizable, globular shell within a central keel. For the first year they can be kept growing through the resting season. Evolution was popularized by the work of 19th century British naturalist. Jamie Anderson, When the date of the rocks is determined using index fossils, these rocks can be further studied to help find the period when the fossils were created. 1.8 million years ago.

If a rock layer contained a fossil of the extinct sea snail Nerinea trinodosa, evolutionists would classify the rock layer as Jurassic and assign it a date of 150 to 200 million years old. In the latter case, trait evolution could still occur through modification of rates of morphological change along otherwise conserved ontogenetic trajectories. In the layer of rock below the amber, the fossilized remains of Nerinea trinodosa were also found. For photos of some of the hybrids consult the Nerine Hybrids wiki page.
