This year has gone by fast! There are only 44 more days left of 2023 so to celebrate I’m gonna make a post about five extinct animals that were described this year!
1. Bos primigenius thrinacius n. ssp.

This new sub species of Aurochs lived on the Greek island of Kythera during the Late Pleistocene. The sub species was probably present on Kythera while it was still part of the mainland, but became trapped when it was separated sometime during the Middle to Late Pleistocene and their small size was a result of insular dwarfism. Insular dwarfism is a common phenomenon in evolution where a population of large animals becomes trapped on an island and slowly evolve to become smaller over time to better adapt to the reduced space and resources. The opposite, insular gigantism, where an island-bound population of small animals grows larger than their mainland counterparts also occurs regularly. During the Pleistocene, the various islands of Greece were full of giant swans and miniature elephants but now we know they had tiny cattle roaming about as well.
2. Garumbatitan morellensis

Meaning “Garumba Giant”, Garumbatitan morellensis was a species of sauropod dinosaur that lived during the Cretaceous period in what is now Spain. Its remains were first discovered in 1998 at the Arcillas de Morella Formation near the city of Morella, however, they would not be excavated until an expedition in 2005. More material would later be discovered in a 2008 expedition and a paper would be published on the findings in 2016, but it wasn’t until this year that the species was officially named and described. Its genus named is a mix of the name for the tallest mountain in the region it was discovered in, Mola de la Garumba, and the Greek word “Titan”.
3. Nihohae matakoi

Nihohae matakoi was a species of dolphin that belonged to the now extinct Waipatiid family and lived during the Oligocene in the waters surrounding what is now New Zealand. It possessed a bizarre set of tusk-like teeth that protruded from its beak. It is thought that this dolphin used it’s strange teeth much like a sawfish to stun their prey before consuming them. The holotype specimen was discovered all the way back in 1998 in Awamoko Valley on New Zealand’s South Island. The specimen consisted of a nearly complete skull, a single atlas and axis, eight vertebrae, and seven ribs. However, Nihohae matakoi would not be officially described until 2023. Its genus name combines the Māori words “Niho”, meaning “teeth”, and “Hae”, meaning “slashing”. The species name is also derived from Māori and comes from the words “Mata”, meaning “face” or “point”, and “Koi”, meaning “sharp”.
4. Perucetus colossus

Another cetacean, Perucetus colossus was a species of early whale that lived during the Bartonian age of the Middle Eocene and was found in Peru (obviously). The remains we have or Perucetus are pretty fragmentary, but it has an estimated length of around 55.8-65.9 ft and was probably just as, if not heavier, than the modern Blue Whale. Due to the density of its bones and its absolute chonkiness, Perucetus likely was not a fast swimmer and likely lived in shallow waters and fed on crustaceans and mollusks. However, this is just speculation as very little about its ecology is known.
5. Vectipelta barretti

Vectipelta barretti was an ankylosaurian dinosaur that lived during the Early Cretaceous in what is now England. It was discovered in the Wessex Formation and it’s genus name means “Isle of Wight shield”. The holotype specimen of Vectipelta was originally discovered in November of 1993, however, at the time it was believed that the specimen belonged to the genus Polacanthus. In May of 2021 it was discovered that the specimen was in fact a new genus and in June of 2023 it was officially named and described. Funnily enough, fossil evidence suggests that Vectipelta might be millions of years older than Polacanthus, the genus it was originally thought to be a member of.
I hope you all enjoyed reading about these recently described prehistoric species! I LOVE dinosaurs and other extinct animals and can’t wait to see what new discoveries 2024 has to offer!
