“Recent”
Yes, in terms of lunar geography 1 billion years is recent. Most lunar features formed 4 billion years ago.
Were the Winter Olympics recent? Not to the E. coli living in your gut.

The Late Heavy, as I like to call it. Sounds like a Drum and Bass producer. Anyways:
The Late Heavy Bombardment (LHB), or lunar cataclysm, is a hypothesized astronomical event thought to have occurred approximately 4.1 to 3.8 billion years (Ga) ago,[1] at a time corresponding to the Neohadean and Eoarchean eras on Earth. According to the hypothesis, during this interval, a disproportionately large number of asteroids and comets collided into the terrestrial planets and their natural satellites in the inner Solar System, including Mercury, Venus, Earth (and the Moon) and Mars.[2] These came from both post-accretion and planetary instability-driven populations of impactors.[3] Although it has gained widespread credence,[4] definitive evidence remains elusive.

The Late Heavy Bombardment has increasingly been called into question.
Here’s one article about it: https://phys.org/news/2016-10-apollo-era-evidence-late-heavy...
The “definitive evidence remains elusive” from your quote is probably a hint: the LHB was a result of getting carried away extrapolating from the Apollo samples due to an early dearth of data, not a real phenomenon.

IIUC "recent" in this article means 124 million years ago.
This is after the meteorite killed "all" the dinoraurs.
Also, North America was joined to Eurasia, South America to Africa, Australia to Antartica, and India was a huge island in the middle of the "Indic" ocean.
Am I right?

The meteorite believed to have killed the dinosaurs was about 66 MYA, https://en.wikipedia.org/wiki/Cretaceous%E2%80%93Paleogene_e... - which is more recent than 124 MYA.
