My understanding is that the impact was at an angle, and threw a fan of superheated material over North America that scoured most of the continent (some limited areas appear to have been shadowed by mountains or other high ground) that wiped out exposed plant and animal life. The rest of the globe was impacted indirectly by the ash and dust of this event, leading to nuclear winter and heavy ashfalls causing further extinctions.
is it possible that the compy types scavenged off all of the piles of already cooked meat like it was xmas dinner buffet and thrived?
A single stash of lots and lots of meat isn’t going to hold you through five years or so of nuclear winter.
If they did, it wasn’t for long, since they didn’t survive.
Do we actually KNOW they all died from the Chicxulub event?
Is it possible some smaller species did survive? Very few species last all that long - in geologic terms - and they could have gone extinct later from other causes.
Some way may, it is disputed.
From time to time there have been claims of dinosaur remains from after the KT event. However, the claims I am aware of are for less than one million years after the event.
The champsosaurs were a crocodile-like group (but not actually crocodilians) that survived the event only to become extinct in the Eocene.

Happy New Year
Angle doesn’t matter in high-speed impacts unless it is very shallow angle. The explosion of rock from the impact is going to be much bigger than the physical size of the impactor itself. That’s why the vast majority of all astroblemes you see on Earth or other bodies are round. The Chicxulub crater is deeply buried now, but it seems to be a normal circular complex crater.
Because your very first action was to deliberately EXCLUDE them from your definition?
If so their fossils would be found above the K-T layer.
Well, that’s obvious. But to assume we have the entirety of the fossil record is just not supported. We’ve identified fewer than what, a thousand, dinosaurs? We have a fraction of a fraction identified. I don’t think it’s unreasonable to assume that if some did survive we haven’t yet found them. I’m asking whether there’s evidence of any kind that would indicate survival.
No, he didn’t exclude them. He only excluded the avian dinosaurs. There were lots of small feathered non-avian dinosaurs. Some of them even flew.
“Avian dinosaurs” refers to one specific lineage among the theropods, the one to which modern birds belong. There were lots of other very birdlike dinosaurs that were not in this lineage.

But then, we have a name for that one particular clade because they’re the ones that survived. If others had survived, too, then we’d use a broader definition for “avian”, which included them too.
Eh, the consensus may change. But in itself, plants not going extinct doesn’t rule out a fire – plants notoriously can survive as buried seeds, tubers, rhizomes and roots and recover from fires.
I dont think so, but I am not the expert on what is a “bird”. Colibri, what do you think?
Sarracenia benefits from burned over areas.
That reminds me–I have lots of photos where I’ve stalked your relatives.
I’ve always pictured him as more like this.
