Hiya guys, just wondering if this could be a plant fossil? Found it on a shipment of paving stones which were quarried in India

These markings, made by the inorganic growth of manganese oxide, are not fossils, but look so convincingly like plants that they are often termed "pseudofossils".  This particular type is known as a "Dendrite".  It formed when an iron and manganese-rich solution percolated down a crack or bedding plane in the sediment and precipitated out the mineral in a characteristic fractal pattern.  Ice can grow in a similar pattern on glass.  Yours are particularly good examples.

Thank you for the detailed reply 😉

The markings cover a slab that is 20x33 inches.

Would be nice to clean up the slab and preserve the markings.
