A modestly amusing footnote in the Loeb edition of Apollonius’ Argonautica (1.55ish), as the poet enumerates the crew.
And from wealthy Gyrton came Caeneus’ son, Coronus—a brave man, but no braver than his father. For bards sing of how Caeneus, although still living, perished at the hands of the Centaurs, when, all alone and separated from the other heroes, he routed them. They rallied against him, but were not strong enough to push him back nor to kill him, so instead, unbroken and unbending, he sank beneath the earth, hammered by the downward force of mighty pine trees*
They drove him into the underworld like a peg, hence he perished while still alive; cf. Pindar, fr. 128f.
ἤλυθε δ᾿ ἀφνειὴν προλιπὼν Γυρτῶνα Κόρωνος
Καινεΐδης, ἐσθλὸς μέν, ἑοῦ δ᾿ οὐ πατρὸς ἀμείνων.
Καινέα γὰρ ζωόν περ ἔτι κλείουσιν ἀοιδοὶ
Κενταύροισιν ὀλέσθαι, ὅτε σφέας οἶος ἀπ᾿ ἄλλων
ἤλασ᾿ ἀριστήων· οἱ δ᾿ ἔμπαλιν ὁρμηθέντες
οὔτε μιν ἀγκλῖναι προτέρω σθένον οὔτε δαΐξαι,
ἀλλ᾿ ἄρρηκτος ἄκαμπτος ἐδύσετο νειόθι γαίης,
θεινόμενος στιβαρῇσι καταΐγδην ἐλάτῃσιν
The Pindar fragment (with the Loeb edition by the same editor/translator as Apollonius) is:
128f The same papyrus gives scraps of vv. 3–8. A scholion on Apollonius Rhodius, Argonautica. “Apollonius took it from Pindar, who said” (vv. 7–9):

But Caeneus,6 (struck with) green (fir trees)
disappears after splitting the earth with his upright
foot.Cf. Plutarch, The Stoics Talk More Paradoxically Than the Poets. “Pindar’s Caeneus used to be criticized for being an implausible creation—invulnerable to iron, feeling nothing in his body, and finally having sunk unwounded under the ground, ‘after splitting the earth with his upright foot.’”
But the best telling is Ovid’s (Metamorphoses 12.490is) in Nestor’s version of the battle of the Centaurs and the Lapiths:
Now, quite beside themselves, the double monsters rushed on with huge uproar, and all together against that single foe they aimed and drove their weapons. The spears fell blunted, and Caeneus, the son of Elatus, still stood, for all their strokes, unwounded and unstained. The strange sight struck them speechless. Then Monychus exclaimed: ‘Oh, what a shame is this! We, a whole people, are defied by one, and he scarcely a man. And yet he is the man, while we, with our weak attempts, are what he was before. Of what advantage are our monster-forms? What our twofold strength? What avails it that a double nature has united in our bodies the strongest living things? We are not sons of any goddess nor Ixion’s sons, I think. For he was high-souled enough to aspire to be great Juno’s mate, while we are conquered by an enemy but half-man! Come then, let us heap stones and tree-trunks on him, mountains at a time! let’s crush his stubborn life out with forests for our missiles! Let sheer bulk smother his throat, and for wounds let weight suffice.’ He spoke and, chancing on a tree-trunk overthrown by mad Auster’s might, he hurled it at his sturdy foe. The others followed him; and in short time Othrys was stripped of trees and Pelion had lost his shade. Buried beneath that huge mound, Caeneus heaved against the weight of trees and bore up the oaken mass upon his sturdy shoulders. But indeed, as the burden mounted over lips and head, he could get no air to breathe. Gasping for breath, at times he strove in vain to lift his head into the air and to throw off the heaped-up forest; at times he moved, just as if lofty Ida, which we see yonder, should tremble with an earthquake. His end is doubtful. Some said that his body was thrust down by the weight of woods to the Tartarean pit; but the son of Ampycus denied this. For from the middle of the pile he saw a bird with golden wings fly up into the limpid air. I saw it too, then for the first time and the last.
ecce ruunt vasto rabidi clamore bimembres
telaque in hunc omnes unum mittuntque feruntque.
tela retusa cadunt: manet inperfossus ab omni
inque cruentatus Caeneus Elateius ictu.
fecerat attonitos nova res. ‘heu dedecus ingens!’
Monychus exclamat. ‘populus superamur ab uno
vixque viro; quamquam ille vir est, nos segnibus actis,
quod fuit ille, sumus. quid membra inmania prosunt?
quid geminae vires et quod fortissima rerum
in nobis natura duplex animalia iunxit?
nec nos matre dea, nec nos Ixione natos
esse reor, qui tantus erat, Iunonis ut altae
spem caperet: nos semimari superamur ab hoste!
saxa trabesque super totosque involvite montes
vivacemque animam missis elidite silvis!
massa premat fauces, et erit pro vulnere pondus.’
dixit et insanis deiectam viribus austri
forte trabem nactus validum coniecit in hostem
exemplumque fuit, parvoque in tempore nudus
arboris Othrys erat, nec habebat Pelion umbras.
obrutus inmani cumulo sub pondere Caeneus
aestuat arboreo congestaque robora duris
fert umeris, sed enim postquam super ora caputque
crevit onus neque habet, quas ducat, spiritus auras,
deficit interdum, modo se super aera frustra
tollere conatur iactasque evolvere silvas
interdumque movet, veluti, quam cernimus, ecce,
ardua si terrae quatiatur motibus Ide.
exitus in dubio est: alii sub inania corpus
Tartara detrusum silvarum mole ferebant;
abnuit Ampycides medioque ex aggere fulvis
vidit avem pennis liquidas exire sub auras,
quae mihi tum primum, tunc est conspecta supremum.
