Description
Well, yes you aren't dreaming, I didn't give up and I present you this: The fifth part of my size chart.
For the people who believed that there is any hope left, it's my turn to say, you're welcome.

Let's begin:

1) Polycotylus sp. (‬very cupped vertebra‭).‬
Diet: Piscivore/Carnivore.
Size: from 3 to 5 metres long, unknown weight.
Time Period: Campanian to Maastrichtian of late Cretaceous (83.6-66 M.y.a).
Region/Known location: USA, Kansas-Niobrara Formation.
Enemies/Rivals: Larger marine predators such as mosasaurs and sharks.

2) Stratodus apicalis ("stratosphere tooth").
Diet: Filter feeder/Piscivore?
Size: up to 5 metres long but it's size remains uncertain, unknown weight.
Time Period: Late Santonian of late Cretaceous to Eocene? of Paleogene (84.9-48.6 M.y.a).
Region/Known location: Alabama-Mooreville Chalk, Israel, Mali & Niger.
Enemies/Rivals: Larger marine predators such as mosasaurs and sharks.

Polycotylus and Stratodus are in comparison to each other but not to the rest of the animals.

3) Plioplatecarpus primaevus ‭(‬More flat wrist‭).
Diet: Carnivore
Size: 5.5 metres long and 500 kg weight.
Time Period: Campanian of the late Cretaceous (83.6-72.1 M.y.a).
Region/Known location: USA, Alabama-Demopolis Chalk Formation.
Enemies/Rivals: Larger mosasaurs and sharks such as Cretoxyrhina.

4) Globidens alabamaensis (''Globe teeth").
Diet: Durophagous (prey included mollusks, turtles but also other creatures as well).
Size: 6 metres long and ~650 kg weight (here it's a bit larger at around 6.5 metres long).
Time Period: Campanian to Maastrichtian of late Cretaceous (83.6-66 M.y.a).
Region/Known location: USA, Alabama-Demopolis Chalk Formation.
Enemies/Rivals: Larger mosasaurs and sharks such as Cretoxyrhina.

5) Archelon ischyros (‬Ruling turtle‭).
Diet: Obligate carnivore (from jellyfish to other small creatures).
Size: 4 metres wide, 4.6 metres long and 2,200 kg of weight.
Time Period: Campanian of the late Cretaceous (80.2-74.2 M.y.a)
Region/Known location: USA, South Dakota and Wyoming.
Enemies/Rivals: Large mosasaurs and sharks such as Cretoxyrhina.

6) Cretoxyrhina mantelli (Cretaceous jaws).
Diet: Carnivore.
Size: 7 metres long and 3 tons of weight.
Time Period: Cenomanian to Campanian of late Cretaceous (94.3-72.1 M.y.a.).
Region/Known location: USA}Alabama-Mooreville Chalk, New Jersey, Kansas, Colorado, Canada, Sweden, Jordan, France & Congo.
Enemies/Rivals: Large mosasaurs such as Tylosaurus.

Both of the scale bars are 1 metre long.

I included Archelon because it's an famous animal from West Interior Seaway despite the fact that it didn't live in Appalachia.
And just to inform, Polycotylus and Stratodus are isolated from the others because their sizes are uncertain.
