The La Brea tar pits don't actually contain dinosaurs.  They are much
newer and only contain relatively recent animals like mammoths and
saber tooth tigers (as well as non-extinct animals).  They go back tens
of thousands of years, thousands of times less than the time interval
to the dinosaurs.  Comparatively speaking, the tar pits are a modern
day phenomenon.  The only reason that the animals in the tar pits are
extinct is because of a mass extinction event in North America which
roughly coincided with the introduction of humans to the continent.

As you probably know, that's not the conventional scientific explanation.
My advice is to give more credence to the belief which is widely held
by experts who have devoted their lives to the study of the field.
