There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.

There were already 3 two topics about rhinos inside Wildfact forum... You can see that by making a search...

https://wildfact.com/forum/topic-conserv...o#pid60600

https://wildfact.com/forum/topic-western...officially

And also:

https://wildfact.com/forum/topic-big-herbivores

And as concerns extinct animals, more precisely fossil rhinos:

You are one of the most valuable posters in this forum, but in this case you are very wrong. WildFact specializes in quality BIG CAT information. Very little is here on rhinos and other herbivores. Even the Asiatic elephant does not have its own thread. The inspiration for creating this thread is Dr Kees Rookmaaker. About him. He is the Chief editor of Rhino Resource Center, the internet's largest collection of information about rhinos. Information from his books will be published later.

The Mammalian Species account of all five extant rhinoceros. About the 'Mammalian Species':

"Mammalian Species is published by the American Society of Mammalogists with 10-20 individual species accounts issued each year. Each uniform account summarizes the current understanding of the biology of an individual species including systematics, distribution, fossil history, genetics, anatomy, physiology, behavior, ecology, and conservation. The accounts vary from 2-14 pages depending upon what is known about the species."

@TheHyenid76 :

You wrote at #3 : " You are one of the most valuable posters in this forum, but in this case you are very wrong. WildFact specializes in quality BIG CAT information.

I'm agree with you Wildfact is very focused by big cats information. But simply because a majority of forumers (myself included as concerns lions) are specially interested by the big felids. When we consider this forum name, I can conclude that it initially concerned the animal life into the wild. I'm not "in the creators' head" but it was my first clear impression when I saw it (Wildfact forum) for the first time. You have just to read the Peter's paraph when you enter this site.

So, the first purpose of this forum was the study and accounts about the wild life. But because of the forumers affinities and interests, the site became a forum specialised about the big cats. We can regret it, because rhinos and elephants for example. whom you quoted about, are also fascinating animals, I clearly think it, but it's so. And don't get me wrong as concerns my remark (#2) but having been a much more activ member during a certain time I initiated several, hardly at all restarted then, topics. and by telling you that, I only wanted to avoid too that your initiated topic stagnates at two or three posts. Because you can understand with me that numerous threads with only 2 or 3 posts don't help to the brightness of the site.

And thank a lot for the numerous links you give about rhinos. I will look at them later... And comment on this thread.

The Historical occurence of Asian rhinos in Bangladesh.

Bangladesh is a small south Asian country surrounded by India and Myanmar with the Bay of Bengal to its South. Historically, Bangladesh had a huge array of incredible megafauna including rhinos. However, rhinos have been extirpated from Bangladesh. Bears, leopards, tigers and elephants are still surviving in the country despite Herculean threats.

From "Red List of Bangladesh Volume 2: Mammals" The Sumatran rhino, Indian rhino and the Javan rhino all have been included in 'Extinct Mammals of Bangladesh'

Occurrence of the rhinos in the Sundarbans

An incredible paper by Dr Kees Rookmaaker on the historical occurrence of the Javan rhino in the Sundarbans. LINK

RECORDS OFTHE SUNDARBANS RHINOCEROS (Rhinoceros sondaicus inermis) in India and Bangladesh

SUMMARY

The Javan rhinos existed in the forests near the Bay of Bengal, called the Sundarbans, in southern Bangladesh and the state of West Bengal, India. It was first shot by F. V. Lamarepicquot in 1828, whose two specimens were described as a new species, Rhinoceros inermis, by Lesson in 1838. The animal was noted in the Sundarbans with some regularity until 1892. In total 11 specimens are known in different museums. The rhinos lived in small numbers in well-defined localities throughout the entire Sundarbans. It must have become extinct before 1925. 

[Map of the Sundarbans of India and Bangladesh. The numbers show localities where rhinos were sighted, see Table 1.]

From "The Imperial Gazetteer of India Volume 13" Year 1885.

"In the Sundarbans, however, the tiger, leopard, rhinoceros, wild buffalo, spotted deer, hog-deer, barking deer, and bara singhar or large deer are common."

Rhinos in Bangladesh outside the Sundarbans. 

From "A preliminary wildlife survey in Sangu-Matamuhuri Reserve Forest, Chittagong Hill Tracts, Bangladesh" LINK

Notes on extinct Megafauna

"The Mro people claim that Banteng never occurred in this area but that wild water buffalo still exists in the area. It can be safely assumed that rhinoceros no longer exist in this part of the CHT. A 90-year-old Mro man mentioned that he encountered a rhinoceros 70 years ago in the Sangu-Matamuhiri Valley."

From 'Mammalian Species Rhinoceros sondaicus' by Dr Colin P. Groves LINK

[Rhinoceros sondaicus occurs in only 2 very small areas of southeastern Asia: Ujung Kulon, West Java (about 6u459S, 105u159E), and Cat Loc, Vietnam (about 11u359N, 107u229E; perhaps extinct). Green shading delimits areas of known historical distribution based on museum specimens collected beginning in the mid-1800s (Groves 1967; Rookmaaker 1980).]

Key points from this post:
  • Historically all the species of Asian rhino species were found in Bangladesh.
  • Javan rhinos were found throughout Bangladesh including the Sundarbans and the Chittagong Hill Tracts. Javan rhinos existed on both the Indian and Bangladesh side of the Sundarbans.
  • Sumatran rhinos were found throughout eastern Bangladesh. (Both north & South)
  • Where the rhinos existed, elephants, bears & wild cats (small and big) still survive. It is important to learn from the extinction of rhinos, and conserve and study the remaining megafauna.
