While there are many large igneous provinces similar to the deccan traps (for example the siberian traps associated with the Great Dying), we don't really have any good evidence for large asteroid impacts comparable to chicxulub so it's tough to say with confidence what effects were directly the result of it versus coincidental. |

The Great Dying you speak of happened to coincide with an asteroid crater off the coast of Antarctica [0]. I haven't been able to find an accurate globe of the continents at that time ([1] doesn't show the poles in great detail), but it does look like eastern Siberia was at the antipode of the Australia/Antarctica boundary. So the theory seems to hold up -- at least from the confines of my armchair, that is.
