there tends to be a lot of obsidian flakes and chips in the hearth ashes, but no chimney.

A: There is no mistake in copying.

Good question, it makes sense. I don't think it's wrong to use tends, but you can also use tends.

There tends to be is a "quasi-modality" of the there be sentence, similar to: there seem(s) to be

The predicate verb (or auxiliary verb) is the same as the subject that follows, and grammatically speaking, a lot of obsidian flakes and chips is plural, so it should be used to be grammatically correct.

However, it is also common to use tends here, and it is more colloquial. Because it starts with a lot of. This is the alternative principle of "proximity consistency".

The proximity is consistent there be, in essence, to take care of our usual habits. We are used to saying: there is a ...

And it is not customary to say: there are a ...So there is a book and two pencils on the desk

Such sentences. The deeper reason is that two vowels together (are and a) are more difficult to pronounce.

And (is a) is easy to pronounce, good to pronounce.

It tends to be the equivalent of it's usually, that is, "it tends to..."This is a fixed sentence, in which tend can be understood as "tending to..."", easy....Is there anything else I don't understand.

a lot of obsidian flakes and chips, which is the main word, is regarded as a whole, and is singular.

Agree with nbyoungor, the answer is very good, this is the difference between formal and informal, written language is still better to use tend, but tends is not wrong, of course it is more flexible in spoken language.

there is the subject of this sentence, therefore, tend is three singles,"Retouching"there is the term.
