令人惊叹的化石蕨 - 植物化石 - Lobatopteris lamuriana (沒有保留價)
A siderite concretion that was split open to reveal an impression of a 3D fern.
Mazon Creek, Illinois, is a famous fossil locality containing plants and animals from 309 million years ago.
These fossils formed from a large flooding event that rapidly buried organisms, allowing for soft parts to be preserved.
This fern fossil was collected in the 1920s in Grundy County.
Very difficult to find in this size and variety today.
Been in storage almost 100 years! From a long ago collection.
Concretion size: 6 x 4 cm
Lobatopteris lamuriana
Moscovian / Desmoinesian
Francis Creek Shale Member, United States of America, Illinois, Mazon Creek Region
