The first trees evolved about 360 Million years ago (according tothis article), and as the brontoscorpio lived underwater, it already couldn't get stuck in tree sap, not to mention, the Silurian period was about 444--419 million years ago (rounded; referenced here ), meaning that trees, and very few land plants (which started adapting to land about 430 million years ago, again referenced to this article). As Diakujia mentioned, the bugs and invertebrates he was talking about was about 300 million years ago, and not the 443.8--419.2 million years you mentioned.

To answer your question, in summary, the brontoscorpio couldn't get stuck in tree sap, meaning it would probably never be included in the mod (unless we're able to get DNA from sandstone from the upper Silurian period.)
