Titanoboa is actually ~14.6 meters and ~2 tonnes (Head, 2013) while Machimosaurus is 1-2 tonnes based on relatives Titanoboa is downsized now. And yes there’s multiple species of Machimosaurus. Update: Yes that study says Titanoboa was 14.6 meters long, but that’s likely an overestimate. Machimosaurus Rex likely weighed 3 tons, according to most sources. Which is heavier than Titanoboa. Also snakes don’t do well with any large reptile their size. |

Burmese pythons can and do take down large alligators. They can't EAT them, sure, but they can kill them.

Actually, most of the time. The American Alligator wins. In fact, Green Anacondas are actually preyed on by Jaguars and Black Caimans.

From
Giant bold snake from the Palaeocene neotropics
reveals hotter past equatorial temperatures (Head et. al 2009)
'Both vertebrae were estimated to be located 60-65% back
along the precloacal vertebral column from the axis-atlas complex.
Regressions of vertebral width from this region against body lengths
for extant boines indicate a snout-vent length (SVL) of 12.01 ± 2.04 m
(39 ft) and a total body length (TBL) of 12.82 ± 2.18 m (42 ft) for
Titanoboa. Incorporating SVL values ofthis study into the relationship
between length and body mass determined for extant Eunectes murinus
(green anaconda)
and Python natalensis (southern African python)
results in an estimated mass for Titanoboa of 1,135 kg (1.27 ton) with a
range of 652 - 1,819kg (0.73-2.03 ton)'
The estimated mass between the respective species, is not extravagant.
Secondly, in your response to someone saying that Machimosaurus did not have impressive weaponry, you link an abstract that speaks nothing on the skull, except for TL, which it is fairly large, it is also pretty longirostrine. It almost reminds me of a false gharial, or the orinoco crocodile.

That doesn't change the fact that constrictors can and will kill large crocodilians readily. Titanoboa is much, much stronger than any constrictor today and can exert an incredible amount of force. Machimosaurus is much smaller in relation to Titanoboa than the Anaconda is compared to the black caiman or the python to the alligator. In the modern world these crocodilians are usually longer and larger than the anaconda. In this matchup Titanoboa is almost the same weight and is much longer and more powerful. |

The largest wild burmese pythons don't exceed 100kg. "large" american alligators weigh as much as several hundred kg. They do not take down large alligators. They prey upon young alligators, or alligators that are/ have attained sexual maturity recently (~1.8mTL), and i haven't seen any substantial evidence of them "taking down" alligators that outweigh them by any significant degree. frankly, there's nothing wrong with that at all. |

Titanoboa. It may not be able to consume Machimosaurus, but Machimosaurus doesn't have weaponry that would outright end the fight. Titanoboa's impressive strength pulls it through here. Not impressive weaponry? The discoverers seem to disagree: www.sciencedirect.com/science/article/pii/S0195667115301178?via%3Dihub. From what I can tell, it's a generalist, similar to modern crocodilians denis , it's true that it's probably a fish eater, but it still has the tools to win along with probably a mass advantage I never said it didn't have 'impressive' weaponry, I simply said its arsenal won't give it the definite win. Titanoboa's strength will, especially if it gets the first strike. |

Kekistani and Ceratodromeus, my mistake.
I may have misread the post, and I thought the article said Machimosaurus was a turtle crusher.
In any case, if Machimosaurus is anything like a gharial then this is onesided in Titanoboa's favor.

He's rather prone to saying stuff is 'likely' without actually backing it up as to why it is. |

dinosauria101Well, even false gharials will eat turtle occasionally; cheloniophagy was proposed due to the abundant turtle remains found in the deposits M.rex was found in, according to the description paper of the species. ". As in other Machimosaurus (in particular, M. hugii, Young et al., 2014b,c), the low-crowned, sub-globidont dentition of M. rex supports a generalist-durophagous feeding ecology. The abundance of turtle remains in the M. rex quarry, including large-bodied forms with length approaching 1 m, suggests that chelonians were a significant part of the diet also in the Tunisian taxon"

Even water monitors will eat turtles, and komodo dragons have a bite force smaller than house cats so the water monitor is likely to have an even weaker bite force

That has so incredibly little to do with what i said, i don't know why you said it.
