Covers comparative evolution and explains how groups adapted to marine environments. Nomenclature-all the subfamilies, etc. was confusing and the evolutionary tree was hard to understand. It would have been good to be able to see all the groups at once on the tree. Liked the updates on research and the maps showing where specimens have been found, Could have gone into the geology a little more.

There is a great deal of content in this course and as always the course materials are excellent. I would prefer at least two presenters to break up the style of the single presenter used. I find his presenting style quite hard. He sounds patronising when he introduces the quizzes and his pronunciation is at times rather odd. Phil Currie could teach him a thing or two.

It's pretty good, though be prepared to be beaten to death with MANY often confusing and nearly unpronounceable taxonomic terms. Can't be helped I guess. Those who took the early vertebrate evolution course will be pleased to note that Mr. (Dr.?) Persons is a bit more subdued in this one with a bit less theatrical style.

Very cheerful and concisely-speaking instructor! Although the course was vast in information to take it all in and could do better with more questions and quizzes. Very educative videos and data about ancient marine reptile palaentology. Beautiful course!

This course is a great gateway into this fascinating part of our earth's history, I look forward to learning more from other courses that are offered and would highly recommend this course to others.

Loved learning about these animals and learned a lot of things I didn't know already but the amount of video content each week was too much the theropod/bird class progressed in a much nicer manner.

Can be extremely complicated with all of the unfamiliar names, and I'd lose focus. As a result, I had a hard time keeping up. I'd recommend pausing and returning another day if you lose focus.

Very informative and well presented. The videos could perhaps have been a little shorter. More videos of c. 15 mins are more readily digestible than fewer at c. 30 mins.

excellent course would love to see more on early crocodilians and turtles, I know turtles have a debated history but would be awesome to look at possible origins.

Thank you for a wonderful course. Ancient Marine Reptiles isn't my main area of interest and I still enjoyed every second!

It was okay, could do better with explaining but still would recommend to anyone interested in paleontology.

I would like more information about taxonomy an evolution. The couse focus mostly in the aquatic problem

Great course! Very well done. The only flaw: subtitles in some lessons are not in syncro with video.

really enjoyed. links didn't work (embedded multiple choice quizzes did work though). thanks!

A very interesting course, but it's a pity one can only do the quizzes after payment.

ive very much enjoyed course and found some things i did not know previously

Its good but I wished it would have more details, but overall its great! :)

Nice intoductory course. More questions and quizes would be nice. Thx!!

It would be great if even the auditing students cool take the quizzes.

Good content in videos - readings were also well done thanks

Great course, interesting topics and explanations, thanks !

very well presented course

While the information presented in the course is top-notch, it's held back by the use of Flash for many interactive aspects of the videos and also large PDFs for the reading material. Flash is an outdated app that is not terribly secure; I'm unwilling to download it just for a free course. That meant I had to skip valuable learning material that really ought to have been presented in some other way; Flash is just not necessary. As for the PDFs, I realize that is a standard format but these must be exceptionally large files, because each week's reading assignment took 20-40 minutes just to load. That's WAY too long. If the files are that big, break them up into chapters so we can load them and get on with learning.

I hate to only give this 3 stars! The material was excellent (5 stars), it was just so held back by the awkward presentation aspects mentioned above.

The course was pretty informative but it lacked a couple of things. Most important of which was the lack of pictures. I believe that using more pictures of actual fossils can be a lot more helpful. Many examples of fossils being found were mentioned throughout the course but only a handful of them were shown. Showing pictures of the actual fossils excavated helps us to visualise these animals properly.

Le contenu du cours est intéressant et Scott Persons rend le cours dynamique. En revanche les sous titres déclalés en permanence et la non présence de sous titres en français comme annoncé initialement rendent le cours très difficiles à suivre. c'est bien dommage
