Plant fossil? Animal fossil? Formation?

Plant. Those are the external mould impressions from the 'bark' of a Lepidodendron species (scale trees). Early Carboniferous to late Triassic, typically ~359.2–205 million years old. Nice specimen.

Thanks,

In all my years collecting this is my first Lepidodendron.
