these parasitic, chinless fish use their disk-shaped sucking mouths and a round row of teeth to bite and bite the host fish. Although the appearance of lamprey is creepy, it is now considered as a delicacy in some countries because of its rich taste and meat quality.

, but this strange-looking fish was especially precious among medieval English gourmets hundreds of years ago. In fact, Henry I died in 1135 at the age of 68. It is said that he ate "a lot of lamprey" against the doctor's orders. According to his chronicle, Henry of Huntington. [photo: the weirdest fish]

Although lamprey often appears in historical records, it hardly leaves any trace in archaeological records. This may be because the bones in the body of lampreys are made of cartilage, and the teeth are made of keratin (the same substance as hair and nails). These two materials are unlikely to survive after being buried underground for centuries. (Lamprey's remains are only found in two other archaeological sites in Britain) "kdspe", "kdspe" and "kdspe", so it was particularly exciting when Alan Pipe, a senior archaeologist at the London Archaeological Museum (MOLA), dug

near the London Mansion Station and found several rows of things that looked like the teeth of seven lampreys in a submerged cesspit. Pipe and his team concluded that the lamprey may have been eaten sometime between 127 and 14, when the cesspit was still in use.

"Almost all the information we know about the popularity of lamprey in medieval England comes from historical records," said Pipe in a statement from MOLA. After studying animal remains for 33 years, we finally found the elusive traces of lamprey in the center of this historic city of London, which were preserved in the flooded fields near the Thames.

the lineage of lamprey has existed for 36 million years. Leymus chinensis is one of the three common species in Britain (the other two are brook lamb and alpaca), and now they are all protected species. Officials of "KDSP" and "KDSP" Mora said that the excavation work near the building has been completed, and the teeth and other findings are still being analyzed. About life science.
