Two paleontologists from National Taiwan University (NTU) have discovered an endemic Taiwanese species and the largest known reptile in Taiwan’s natural history, after spending four years re-examining fossils from an extinct crocodile.
In a Facebook post on Friday last week, NTU said the reptile, named Toyotamaphimeia taiwanicus, was discovered by Tsai Cheng-hsiu (蔡政修), an associate professor in the university’s Department of Life Science, and Cho Yi-yang (卓義揚), a master’s degree graduate from its Institute of Ecology and Evolutionary Biology.
It had been mistakenly identified before by Japanese academic Tokio Shikama as a Taiwanese Malay crocodile, which existed during the Pleistocene, the university said.

The extinct reptile was estimated to reach up to 7m in length, making it the largest reptile in the country’s natural history and also larger than any extent species of saltwater crocodile.
The crocodile fossils were discovered in Tainan in 1972 by Shikama.
Tsai and Cho borrowed the fossils from Japan’s National Museum of Nature and Science and brought them to Taiwan, NTU said.
CROCODILE PRINCESS
The fossils had been named after “Toyotama,” a mythological Japanese princess, who, according to legend, turned into a crocodile, NTU said.
The university said that Taiwan now has its own “crocodile princess” and it is thought to be related to the also extinct Toyotamaphimeia machikanensis, which was discovered in Osaka, Japan, in the 1960s.
The study might help address the reasons and causes of extinction in Taiwan and the wider issue of how climate change is contributing to the sixth mass extinction crisis, it said.
The research was first published in the Journal of Paleontology on June 29.
A strong continental cold air mass is to bring pollutants to Taiwan from tomorrow, the Ministry of Environment said today, as it issued an “orange” air quality alert for most of the country.

Taiwan’s armed forces have established response protocols for a wide range of sudden contingencies, including the “Wan Chun Plan” to protect the head of state, the Ministry of Defense (MND) said today. After US President Donald Trump on Saturday launched a series of airstrikes in Venezuela and kidnapped Venezuelan President Nicolas Maduro, concerns have been raised as to whether China would launch a similar “decapitation strike” on Taiwan. The armed forces regularly coordinate with relevant agencies and practice drills to ensure preparedness for a wide range of scenarios, Vice Minister of National Defense Hsu Szu-chien (徐斯儉) told reporters before a
EVA Airways on Saturday said that it had suspended a pilot and opened an investigation after he allegedly lost his temper and punched the first officer several times as their plane was taxiing before takeoff at Los Angeles International Airport. According to a report published on Thursday by The Reporter, the incident occurred after the flight’s Malaysian first officer tried to warn the Taiwanese pilot, surnamed Wen (文), that he was taxiing faster than the speed limit of 30 knots (55.6kph). After alerting the pilot several times without response, the first officer manually applied the brakes in accordance with standard operating
