Dinosaur-killing asteroid was a rare rock from beyond Jupiter, new study reveals

Scientists have uncovered the "genetic fingerprint" of the dinosaur-killing Chicxulub impactor, potentially revealing the fateful rock's origins in the outer reaches of our solar system.

Bearing in mind the following from Google:

There may be billions, or even trillions, of objects in it, and some are so large that they count as dwarf planets. Many long-period comets originate from the Oort cloud. Almost all objects that have approached the inner solar system from the Oort cloud are comets made of frozen gas and dust.9 Mar 2023

The Oort cloud is a collection of comets, small km-scale icy (and perhaps rocky) left-overs from the process of solar system formation. It is a spherical collection of bodies orbiting the sun.9 Mar 2023

This article seems to be inconsistent in its statements about where the Chicxulub impactor originated.

It says: "a rare rock from beyond Jupiter" in its title, and "origins in the outer reaches of our solar system" in its subtitle.

But then the story test says "the chemical composition of a rare element called ruthenium to be similar to that within asteroids hovering between the orbits of Mars and Jupiter" and "Ruthenium's chemical signatures in the Chicxulub impactor were consistent only with those of the carbonaceous meteorites" . . . "which dominate the outer region of the main asteroid belt."

So, the story seems to say that the impactor came from the outer parts of the main asteroid belt, which is between Mars and Jupiter, not "beyond Jupiter". And, even Jupiter is not what most people would call "the outer reaches" of our solar system. It is certainly nowhere near as far out as the Oort Cloud.
