Symphyseal A. kopingensis teeth are scarce and have a unique shape. This shark likely had 3 symphyseal files in total.

This is another symphyseal. This one is more robust.

Here is another robust symphyseal.

Upper anterior teeth have symmetrical root lobes and a slightly curved crown. This one is likely an upper second anterior.

This tooth is another upper anterior. It is from the same position as the one above.

This tooth has more symmetrical root lobes and is likely an upper first anterior.

Lower anterior teeth generally have a more erect crown and asymmetrical root lobes (except lower first anteriors). This one is likely a lower second anterior and has the “classical” shape of a lower anterior.

Here is another lower anterior (likely a lower second anterior). This one is probably from a sub-adult.

My largest lower anterior (likely a lower second anterior) at 1 inch.

This tooth has a large lingual protuberance and is most likely a lower first anterior. Lower first anteriors are reduced in size. They are the most symmetrical lower anteriors, but are not as symmetrical as upper A1 teeth.

This A. kopingensis is most likely another lower first anterior (there is a chance that it is actually a sub-adult upper A1); it has a much smaller lingual protuberance than the tooth above.

Intermediate teeth exist only in the upper jaw, in between the last anterior file and the first lateral file. They resemble lateral teeth, but are smaller, less robust, flatter, and less distally curved.

This intermediate has an interesting shortened distal root lobe. A. kopingensis likely possessed 2 intermediate files.

Upper lateral teeth have slightly shorter root lobes than upper anterior teeth. They also have a longer mesial root lobe than distal root lobe and are very distally curved.

This upper lateral is a little more stout than the one above.

This upper lateral is likely from the same tooth file as the first lateral tooth shown.

This tooth is a sub-adult upper lateral. It is likely from the same tooth file as the first and third lateral teeth presented.

This upper lateral tooth came from a tooth file closer to the posterior of the jaw.

This sub-adult upper lateral possesses a distal secondary cusplet and a large mesial cusplet which looks like it was developing into a double cusplet.

Lower lateral teeth are less curved and less robust than the uppers. Lower lateral teeth can seem similar to lower anteriors. Lower laterals are less robust and normally have a less prominent lingual protuberance. They also have a wider and “smoother” angle between the root lobes; lower anteriors have a narrow and “sharper” angle between the root lobes.

Posterior teeth are usually much smaller than the anteriors and laterals. Most of the posterior teeth are likely uppers. This is a relatively large tooth for a posterior and is from one of the first posterior tooth files.

Another large posterior tooth. This one has a massive mesial cusplet.

This posterior tooth is of a more usual size for posterior teeth and has labial wrinkles, a common feature in posterior teeth.

This posterior tooth is even smaller and narrower than the one above.

This posterior is similar to the one above.
