blast from the past // samaras and planorbis

Time for some blast from the past ! While browsing my archives, I stumbled upon these photos, which I loved back then & still love today : samaras (seeds) & planorbis (fossils).

03rd June 2010

⎡ A samara is a type of fruit in which a flattened wing of fibrous, papery tissue develops from the ovary wall. A samara is a simple dry fruit and indehiscent (not opening along a seam). They are winged achenes. The shape of a samara enables the wind to carry the seed farther away from the parent tree. ⎦

These samaras came from an Acer Monspeliensis, a local type of maple from Montpellier region.

⎡ Planorbis is a genus of air-breathing freshwater snails, aquatic pulmonate gastropod mollusks in the family Planorbidae, the ram's horn snails, or planorbids. All species in this genus have sinistral or left-coiling shells. ⎦

The planorbis were found locally too, and are supposed to be 120 millions years old.

If you wonder, what is between the samaras & the planorbis were seeds, and other fossils.

Have a lovely middle of the week !
