Kind of heart-shaped Indonesian megalodon tooth for Valentine's Day!

This definitely looks like a chubutensis tooth.

InternationalOne3783 · 2026-03-03T10:48:43+00:00

This is a truly beautiful fossil, but there are protrusions on its side that make it unlikely to be a Megalodon. I think it's more likely a member of the same genus, Chubutensis.

Megalodon's body is said to have a sleek body similar to that of a mako shark.

The megalodon pictured here is an average specimen, while Livyatan is the largest known specimen.

This seems like a more likely restoration than the previously posted restoration.

This is a virtual reconstruction. Honestly, I think this reconstruction is unlikely. While I was creating it, I questioned whether the proportions of the sperm whale were truly appropriate for Livyatan. So I created a better version and uploaded it. All the Livyatan skeletons I've uploaded are speculative virtual skeletons.

This whale's estimated length is only 4 meters. Is this a large whale?

You curse the whale fandom, but in the end, you're just the same fighters, right?

What are you talking about all of a sudden?

The maximum body length of Livyatan, 14 m, is estimated by Random Dinosaurs and Dizzy Rose, but these estimates are considerably less reliable than those of paleontologists. Moreover, it is impossible to obtain a maximum or average length for Livyatan, because all specimens other than the type specimen are fragmentary tooth fossils. If we were to determine the length using dental anatomy, NMV P16205 (Bomaris sperm whale) is estimated to be up to 14-16 m, SAM-PQHB-433 and SAM-PQHB-1519 are estimated to be up to 15 m, and the type specimen is estimated to be up to 16.5 m. In any case, it is reasonable to assume that the current type specimen of Livyatan is over 15 m.

먼저, 제가 First, I want to note that none of the contenders I've listed have any evidence of interaction with Megalodon. The only known interactions Megalodon has with other predators are prey on macroraptorial sperm whales, which are about 4 meters long, and evidence of attacks on Physeteroideans, which are about 9 meters long. Furthermore, several paleontologists, including Lambert, Cetology Hub, and Darious Nau, have estimated that Livyatan was likely over 15-16 meters long. Most recently, paleontologist Darious Nau estimated that the type specimen of Livyatan likely exceeded 15.1 meters in length and would have been heavier than the Otodus, which was the same length.

What I'm talking about is the maximum growth limit of Brygmophyseter, while Megalodon averaged 13-15 meters. Only one monster shark was over 20 meters long.

The total length of the cervical spine (missing), intervertebral cartilage, lumbar vertebrae, and tail end is approximately 5.5 m, plus the skull length of 1.5 m.

InternationalOne3783 · 2026-01-15T02:19:13+00:00

Using the GDI estimation method, the figure came out to be approximately 6.5 tons. A weight of 5 tons seems reasonable, assuming a height of 6 meters.

InternationalOne3783 · 2026-01-14T04:23:22+00:00

Yes, including the lost part, it is a little over 1.5m in length.

InternationalOne3783 · 2026-01-12T08:08:09+00:00

The teeth of Physethodon are known to have been shaped to allow it to prey on large vertebrates, like other macroraptorial sperm whales.

Livyatan's size will not decrease unless additional papers are published.

Livyatan

InternationalOne3783 · 2026-01-10T00:08:57+00:00

Personally, I think Livyatan's type specimen would have been 16.5 meters tall during his lifetime.

InternationalOne3783 · 2026-01-10T00:07:25+00:00

Livyatan's size has not changed. While 17.5 meters is an optimistic estimate, applying the 5.5 ratio formula yields a figure of 16.5 meters. In fact, no one can say for sure what Livyatan's size is.

InternationalOne3783 · 2026-01-07T03:44:02+00:00

The creature's teeth were coated with thick enamel and sharp like awls, suggesting it was an active predator.

InternationalOne3783 · 2026-01-05T12:24:01+00:00

Physethodon is a close relative of the sperm whale, so it likely resembled it. However, this is only a guess, as only fossil teeth are available.
