For version 59.0 onwards of Prehistoric Nature, the main mod moved out all the complex decorative blocks which have the ability for you to trim then in ores. This was done as these blocks are graphics-intensive and not all players could manage to play the main mod nicely with these blocks inside it, so now they are optional by installing this addin mod.
The blocks included now in the decoration addin mod are:
Rope barriers
Bridges
Benches
Litterbins (they delete items!)
Planters (2 types per wood type and varius soil-types)
