Mankind's fossil record
Various things may survive a large meteorite impact, such as would kill off most of us, but not actually destroy the planet. (There is a geological layer rich in iridium courtesy of one meteorite, see https://en.wikipedia.org/wiki/Iridium_anomaly .)
Indeed the world's geologists are currently considering what is the best geological marker for the start of the current Anthropocene age. My suggestion is lead in the geological record. When Clare Cameron Patterson ('Pat' to his friends) tried to deduce the age of the earth from the relative abundancies of lead isotopes, he discovered that humans had polluted the entire surface of the word with lead, primarily from the use of tetraethylead in gasoline. Everything you can see, eat, drink, touch etc. that is not over 7000 years old or specially refined is polluted with lead courtesy of us starting to smelt metals 7 millennia ago. The use of unleaded fuels now has helped reduce the amount of pollution, but it is still there.
The other noticeable geological feature would be radioactive elements due to air-burst nuclear weapons in the mid 20th century. Other things which may survive could possibly be cut gemstones, and of course the amount of plastics we are putting into the oceans.
One question, does the orientation indicator for North show the direction of North for the rock when it was found, or in the period when the pawprints were made? Don't want to be too controversial, but there are rumours that the continents might have move a tad in the last 140 million years.
